What is time-resolved cathodoluminescence?
Time-resolved cathodoluminescence is a technique in which the time dynamics of the cathodoluminescence emission process is observed.
This presentation will give you an overview of the time-resolved cathodoluminescence techniques: lifetime imaging (or emission decay) and g(2) imaging, which is also known in physics as second-order correlation function.
The SPARC is a high-performance cathodoluminescence detection system designed and produced by Delmic, which offers a unique solution for cathodoluminescence imaging. With the Delmic LAB Cube (a time-resolved CL module) for the SPARC, it is possible to extend the SPARC to do lifetime and antibunching experiments.

PHOTONIC CRYSTALS
Photonic crystals are periodic dielectric structures that have a band gap that forbids propagation of a certain frequency range of light. This property enables one to control light with amazing facility and produce effects that are impossible with conventional optics.Photonic crystals can be fabricated for one, two, or three dimensions. One-dimensional photonic crystals can be made of layers deposited or stuck together. Two-dimensional ones can be made by photolithography, or by drilling holes in a suitable substrate. Fabrication methods for three-dimensional ones include drilling under different angles, stacking multiple 2-D layers on top of each other, direct laser writing, or, for example, instigating self-assembly of spheres in a matrix and dissolving the spheres
Fast-Switching Structural Color to Revolutionize Low-Power Displays
Unlike high-power consuming conventional displays that emit light, reflective displays or the so-called “electronic paper” use ambient light and consume much less energy.
They lack behind, however, in color range and switching speed. Thus, electronic paper technology has been used predominantly for ebook readers and labels that are less demanding of these features.
A group of English and Swedish scholars joined forces to overcome the setbacks. In research published in August 2021 in Advanced Materials, a weekly peer-reviewed scientific journal, they introduced a structural color technology that successfully achieved favorable video speed and image quality.
The wide color spectrum in conventional displays results from the combination of red, green, and blue (RGB)-filtered subpixels. Under the leadership of Andreas Dahlin from the Department of Chemistry and Chemical Engineering of the Chalmers University of Technology in Gothenburg, Sweden, the researchers explored the potential of structural colors to generate the RGB subpixels in reflective displays.
Conventional color is a result of the absorption of light. If an object appears red, it means a dye or pigment absorbs all other colors besides red. Structural color, however, results from the reflection of light from complex colorless nanostructures. Some examples in the natural world include butterflies’ wings and opals. Colors produced by chemical pigments remain unchanged regardless of the angle from which they are viewed. The colors produced by the multi-layered nanostructures, on the other hand, are iridescent; they appear different from different angles. Thus, making structural colors highly suitable for creating colored subpixels.
It is important to note that the team did not use the widely popular liquid crystals. Instead, they used a broadband-absorbing polarization-insensitive electrochromic polymer to sustain a high level of reflectivity.
The researchers started with thin alumina or aluminum films, on top of which they arranged nanoparticles and added an ultrathin gold coating. The created metamaterials boasted a large surface area and increased optical contrast. To regulate the brightness and visibility, the team finished with an opacity-changing conjugate polymer top coating.

MSE PhD lecture. Adv. Mater. Synthesis. Thin Films. Oct 23, 2014.
This document summarizes a lecture on thin film deposition techniques given by Dr. Toru Hara. It begins with definitions of thin films and their applications in electronic devices, optical coatings, optoelectronic devices, and quantum devices. It then provides brief introductions to specific applications like transistors, oxygen sensors, and LEDs. The main deposition techniques are also summarized, including chemical methods like plating, CSD, CVD, and ALD, as well as physical methods like thermal evaporation, sputtering, PLD, and MBE. Examples of equipment schematics are provided for many of the techniques.
PLASMONICS
Plasmonics aims to merge photonics and electronics at the nanoscale by using surface plasmons. Surface plasmons are electromagnetic waves that propagate along metal surfaces and can confine light to subwavelength dimensions, allowing the miniaturization of photonic components. This makes it possible to integrate optical and electronic circuits on the same chip. Plasmonic circuits use various geometries like thin metal films and arrays of gold nanoparticles as waveguides to guide surface plasmon signals while avoiding losses. This could enable the development of miniaturized optoelectronic components and circuits with subwavelength features bridging the gap between photonics and electronics.
Sem and tem
Scanning electron microscopes (SEM) and transmission electron microscopes (TEM) were developed to overcome limitations of light microscopes and enable higher magnification. SEM uses a focused beam of electrons to scan sample surfaces, revealing topography, composition, and other properties. TEM transmits electrons through thin samples to form magnified images and diffraction patterns, allowing visualization of structures like organelles and crystal structures. While both use electron beams, SEM analyzes surface features and TEM transmits through samples, giving each technique different applications and resolution capabilities.
plasmonics pdf
Plasmonics is a new technology that uses surface plasmons to enable faster data transfer. Surface plasmons are oscillations of electrons that can couple with electromagnetic waves. This allows data to be transported using light at the nanoscale. Plasmonics could bridge electronics and photonics by transporting data at optical frequencies but at electronic size scales. Potential applications include faster computer chips using plasmonic interconnects and new cancer treatments using plasmonic nanoparticles.
Photonic crystals
Photonic crystals are periodic optical nanostructures that affect the propagation of light. They contain regions of high and low dielectric constants arranged in a repeating pattern, allowing certain wavelengths of light to pass through while others are forbidden from propagating, known as a photonic band gap. Photonic crystals have applications in lasers, optical fibers, biosensing and more. They can be fabricated through methods like layer deposition, photolithography or drilling holes to achieve one, two or three-dimensional periodicity.
Pulse laser deposition of thin film
This document discusses pulsed laser deposition (PLD), a physical vapor deposition technique used to deposit thin films. In PLD, a high-power pulsed laser beam is focused onto a target material, vaporizing it and creating a plasma plume that expands toward a substrate where the ablated material is deposited as a thin film. Factors like laser parameters, substrate temperature, background pressure influence the nucleation and growth of the deposited film. PLD offers benefits like exact transfer of complex materials and variable growth rates compared to other thin film deposition methods.
Sem
Scanning electron microscopy (SEM) is a technique that uses a focused beam of electrons to image the surface of a sample at high resolutions down to 1-10 nm. The electrons interact with the sample surface to produce various signals containing information about the sample's topography, morphology, composition, and microstructure. Key parameters that influence the electron beam include the accelerating voltage, probe current, aperture size, and working distance, and require optimization for optimal imaging.

Probing Molecular Electronic Structure Using High Harmonic Generation Tomography
The structure of valence electronic orbitals of a molecule determines the majority of chemical properties. Generation of high-order harmonic frequencies from atomic sources has been directly related to the electronic structure of the atom, (1) and extended as far as tomographic reconstruction of linearly symmetric polyatomic molecular systems with some success. (2,3,4)
However, because of the increased resolution of these reconstructions, discrimination of fine details of the orbital reconstructions reveals some inconsistencies in the orbital shapes when compared with past models & theoretical calculations. (2) There are several proposed corrections to the Strong Field Approximation (SFA) that currently underlies tomographic reconstruction as well as all other experiments that use high harmonic generation (HHG) to probe molecular systems. (5,6,7)

Generation of high-order harmonic frequencies from atomic sources has been directly related to the electronic structure of the atom, (1) and extended as far as tomographic reconstruction of linearly symmetric polyatomic molecular systems with some success. (2,3,4)
However, because of the increased resolution of these reconstructions, discrimination of fine details of the orbital reconstructions reveals some inconsistencies in the orbital shapes when compared with past models & theoretical calculations. (2) There are several proposed corrections to the Strong Field Approximation (SFA) that currently underlies tomographic reconstruction as well as all other experiments that use high harmonic generation (HHG) to probe molecular systems.

Self assembly in photovoltaic devices
Self-assembly techniques can be used to construct nanostructures for photovoltaic devices in a cheaper and faster way compared to traditional fabrication methods. The document discusses how self-assembly of porphyrin and fullerene molecules on metal oxide electrodes leads to the formation of clusters that absorb light effectively across the visible spectrum. It also describes how coating aligned ZnO nanorods with TiO2 using atomic layer deposition creates a two-dimensional photonic crystal for enhanced light harvesting in dye-sensitized solar cells. Overall, the document outlines the potential of self-assembly methods to organize functional organic and inorganic materials into nanostructures that improve the performance of organic and perovskite photovoltaics.
Synopsis
This document describes a comparative study of ZnO layers grown using molecular beam epitaxy (MBE) and radio frequency (RF) sputtering techniques. It discusses the properties and applications of ZnO, the deposition techniques, and characterization methods like current-voltage measurement, deep level transient spectroscopy, and photoluminescence spectroscopy. The goals of the study are to understand defects in ZnO grown by different methods and correlate growth parameters with material properties to enable high-performance ZnO-based optical and electronic devices.
Plastic Electronics
Organic electronics such as organic LEDs (OLEDs) and organic photovoltaics (OPVs) offer advantages over traditional electronics like being lightweight, flexible, and having low-cost production. The document discusses the electronic structures of organic materials used in these applications and how they enable charge transport. It reviews the state-of-the-art in OLED and OPV technologies and processing techniques like solution processing and vapor deposition. Photocrosslinking is highlighted as a method to improve device performance. Challenges in improving material properties, device efficiencies, and reducing costs are also outlined.
Photon Extraction: the key physics for approaching solar cell efficiency limits
This document discusses the fundamental limits of solar cell efficiency and the importance of photon extraction. It summarizes that the Shockley-Queisser model obscures important photon dynamics within solar cells. Explicitly designing for photon extraction is key to approaching the theoretical efficiency limits. Small imperfections in material quality or optical design can significantly reduce performance due to the non-linear relationship between efficiency and photon extraction. Recent record efficiencies achieved through improved rear reflectors and photon extraction techniques demonstrate there is still potential to surpass 33% for single junction cells.

The document summarizes simulation results of quantum dot cuboid nanocrystals with different nanostructures. It first describes taking a 3D cuboid structure and simulating its 3D wavefunction, energy states, and light/dark transitions under different polarizations. It finds the characteristics are equivalent for different structures given the same boundary conditions. It then simulates a pyramid structure and finds its absorption peaks differ in number but are otherwise equivalent to the cuboid. The conclusion states that for different nanostructures, the characteristics are almost equivalent under the same boundary conditions.

This document describes research into absorber coatings for use in mid-infrared astrophysics. The researchers created coatings made of epoxy loaded with graphene and glass microspheres, and characterized the materials' dielectric functions and optical properties through modeling and testing. Their coatings were designed to absorb stray light for instruments like SOFIA while withstanding cryogenic temperatures. Modeling showed the coatings had the desired frequency-dependent response, though scattering from microspheres was not fully captured. Further studies measuring optical properties were recommended.
