Diode

Maria Romina Angustia

Diodes are semiconductor components that allow current to flow in only one direction. They have two terminals called the anode and cathode. Current can flow from the anode to the cathode but not in the reverse direction. When a forward bias is applied, the depletion region collapses and current can flow through the diode. When a reverse bias is applied, the depletion region expands and blocks current flow. Diodes are used in applications such as rectifiers, reverse current protection, logic gates, and voltage spike suppression.

Semiconductor and Electronic Circuits

Yong Heui Cho

This document discusses the history and basics of semiconductors and electronic circuits. It covers key topics like the development of early computers using vacuum tubes, the invention of the transistor at Bell Labs in 1948, the first integrated circuits in the late 1950s, and how doping processes are used to dope silicon substrates for semiconductors. The document also provides an overview of basic circuit theory and both passive and active electronic devices.

Semiconductor physics

Speaking Technology

The document discusses the physics of semiconductors including PN junction diodes and resistors. It covers semiconductor fundamentals like doping and intrinsic nature. It describes how doping materials like phosphorus or boron create N-type or P-type semiconductors. When an N-type and P-type material come into contact, a PN junction is formed with a depletion region and electric field. A PN junction acts as a switch that only allows current in one direction depending on whether it is forward or reverse biased.

This document discusses gas-assisted laser cutting of medium-section metals using spherically aberrated laser beams. It analyzes how spherical aberration affects the laser intensity distribution near the focal point through numerical simulations and experiments. Several optical systems were designed with identical parameters except for the noncorrected spherical aberration to produce different intensity profiles. Trial cuts in mild steel were performed to examine how the aberrated intensity profiles impacted cut quality. The results showed that high quality cuts can be achieved with different intensity distributions, but maintaining precise focal point positioning is more important for beams with greater aberration-induced refocusing.

George Botonakis

This document summarizes a dissertation on exploring active and passive mode-locking in fibre ring lasers. It begins with an abstract stating the aim is to optimize pulse shaping in these lasers and directly compare active and passive mode-locking techniques. Section 1 provides background on mode-locking theory and factors that affect pulse formation. Section 2 will discuss active mode-locking using an acousto-optic modulator and optimizing pulse parameters. Section 3 will cover passive mode-locking using saturable absorbers and simulations. Section 4 will modify a passively mode-locked laser to support multi-wavelength generation via four-wave mixing and determine if this enhances performance.

1) The document analytically studies parametric oscillation of optical phonons in magnetized doped III-V semiconductors using hydrodynamic modeling of semiconductor plasmas and coupled mode theory of interacting waves. 2) It derives expressions for the threshold pump intensity and conversion efficiency of a proposed single resonant parametric oscillator using this model. 3) Numerical analysis is performed for an n-InSb crystal laser to analyze the effects of transverse magnetic field, mirror reflectivity, crystal length, and other parameters on the threshold pump intensity and conversion efficiency.

Starting with the introduction to the field of microfluidics and optofluidics, the fundamentals of optofluidics and its advantages are briefly discussed. An extensive survey of the various research works in this field is captured under two broad categories namely, i) optofluidic sources and devices and ii) optofluidic sensors. Recent works on optofluidic DFBs lasers, microcavity fluidic dye laser integrated with lab- on-a-chip systems, fluorescent liquid-core/air-cladding waveguides and microfluidic droplet dye lasers are described. Research on compact refractometers integrated onto planar microfluidic geometry, refractive index sensors based in microfluidic Fabry-Perot cavity, interferometric imaging based optofluidic pressure sensors, sensors based on novel liquid-core optofluidic ring resonators are briefly reviewed. Touching upon the concept of whispering gallery modes, many other applications of optofluidic ring resonators in lasing and sensing are mentioned. Based on the available literature the doctoral research work is proposed under the following themes: I. Design and characterization of optofluidic sources for lab-on-a-chip applications. II. Design and characterization of various optofluidic resonator geometries for biomedical sensing applications. Specific goals are enumerated and the methodology that would be followed is described in detail. The term “optofluidics” was created in a University Research Center funded by the Defense Advanced Research Projects Agency (DARPA) in 2003 to define a developing research field that focuses on combining microfluidic and optical technology. This jargon became extensively adopted in the space of 5 years and applied as a categorical descriptor for a large number of research directions [3]. Optofluidics refers to a class of optical systems that are synthesized with fluids to leverage specific advantages of these two disciplines. Fluids having unique properties that cannot be observed in solid equivalents can be used to design novel devices.

Non Invasive Glucose Measurement using Raman Spectroscopy

IRJET Journal

This document discusses non-invasive glucose measurement using Raman spectroscopy. It begins with an introduction to diabetes and the need for frequent blood glucose monitoring. Current methods are invasive and painful. The document then reviews various non-invasive optical methods studied previously, including near-infrared spectroscopy, photo-acoustic spectroscopy, and optical coherence tomography, which all have limitations. It focuses on Raman spectroscopy, which resolves limitations of other techniques by using inelastic light scattering to obtain a molecular fingerprint spectrum. The methodology section describes the setup, which uses an 830nm laser as the excitation source and collects inelastically scattered light to identify glucose and other molecules for non-invasive concentration measurements.

Organolead halide perovskites are an impressive and relatively recent class of light-absorbing materials for solar cells and light-emitting devices. It has been reported that exposure of the perovskites materials to light has negative impacts on device performance. Also, surface recombination has been reported as a major obstacle to the total carrier lifetime in perovskite polycrystalline thin films. Herein, we explored the role played by Nanosecond pulsed UV laserirradiation on carrier dynamics in perovskites thin films. Steady-state and time-resolved photoluminescence measurements revealed the interplay of disorder and heterogeneity on photoexcited carrier dynamics, while in-situ micro Raman and Angle dispersive X-ray diffraction showed the mechanisms of crystal phase reconstruction. Exposures to laser light leads to rapid crystal phase reconstruction and hence, unexpectedly, extend PL lifetime by fourfold instead of promoting degradation. This verifies nanosecond pulsed laser irradiation plays a beneficial role in improving in optoelectronic material parameters. Our findings reveal that pulsed laser irradiation is a new approach to the reconstruction of microstructure and offers beneficial effects in the manufacture of perovskites solar cells. Moreover, this work provides a clear insight towards identifying the physical origin behind the disorder, heterogeneity, film reconstruction and nano-structuring as well as their correlation with improved PL lifetime. Keywords: perovskites, pulsed laser irradiation, reconstruction, disorder, heterogeneity, photoluminescence

Probability Analysis of Slope Stability Analysis

Conferenceproceedings

1) The paper presents a probability analysis of slope stability using the Monte Carlo simulation method to account for uncertainty in parameters like pore water pressure, cohesion, and internal angle of friction. 2) The results of the Monte Carlo simulation method are compared to other recognized methods of slope stability analysis like Bishop simplified, Fellenuis, Janbu simplified and corrected, Spencer and Lowe-Karafiath which use limit equilibrium. 3) The probability analysis finds that the failure probability is most affected by the standard deviation of pore water pressure, cohesion, internal angle of friction, and correlation coefficient between parameters, though individual limit equilibrium methods only account for one of these parameters in each analysis.

Some Biochemical Markers that Can Predict Pre-Eclampsia

Conferenceproceedings

This document summarizes an abstract from the 9th International Scientific Conference on Applied Sciences and Engineering. The abstract discusses some biochemical markers that can predict pre-eclampsia. It states that tumor necrosis factor alpha (TNF-α) directly damages vascular endothelial cells and increases endothelial permeability, which may result in secretion of vasoactive substances and increased vascular permeability and coagulation. This involvement of TNF-α in the pathogenesis of pre-eclampsia means it may identify patients at high risk for the condition and serve as a marker of severity. Preeclamptic women also have abnormal lipid metabolism and profiles due to pre-eclampsia, and this alteration in lipid metabolism may play a key role in developing symptoms.
