This document is a resume for Kyounkwon Park. It summarizes his education, including a Ph.D. in Electrical Engineering from UCLA in 2014, as well as his technical skills and work experience. Park currently works as a Senior Engineer at Samsung Display Co. designing nanocrystal-based display panels. He has also conducted research at UCLA on topics including quantum dot synthesis and characterization, optical voltage sensing using semiconductor nanoparticles, and nanoscale integrated circuits.
Dr. Gernot S. Pomrenke presents an overview of his program, Photonics and Optoelectronics, at the AFOSR 2013 Spring Review. At this review, Program Officers from AFOSR Technical Divisions will present briefings that highlight basic research programs beneficial to the Air Force.
: Due to the huge power consumption and expensive fabrication methods required, down scaling silicon devices to sub-100 nm dimensions is becoming very unattractive. On the other hand, it is easier to build electronic circuits using molecules since they are small and their properties can be tuned. In this review, we first discuss the building blocks of molecular electronics. We then describe how these building blocks can be used to build single molecule based digital logic such as AND, OR and XOR gates. The distinction of these molecular electronic building blocks is that for first time, (i) the Tour wires are used as the conductive backbone for the rectifying junctions, (ii) donor/acceptor principles are implemented in the molecular wire itself and (iii) the logic gates are realized using molecular rectifying diodes embedded in the molecular conducting wire itself.

This presentation is about the emerging and future possible trends of the exciting field of nanotechnology. Scientists and engineers are working on a smaller scale day-by-day to increase portability and smaller devices, and to change the way we see the world and live in!
Due to the inherent shortcomings of existing antenna technologies (such as array coupling, reconfigurable difficulty, poor RF stealth performance, etc.) or the inability to meet the application requirements under new forms (implantable devices, onboard applications, etc.) A new type of antenna launched a series of studies - liquid antenna, plasma antenna, metamaterial antenna, nano-ray antenna, implantable antenna, foldable antenna.

COUPLED FIELD ANALYSIS OF PIEZOELECTRIC CANTILEVER BEAMijiert bestjournal
Electromechanical modelling efforts in the research field of vibration-based energy harvesting have been mostly focused on forms of vibrational in put as in the typical case of harmonic excitation at resonance. However,ambient vibration al energy often has broader frequency content than a single harmonic. Piezoelectric energ y harvesting is a promising technology for extracting the power from environmental vibrations. It generates the electrical power of few orders of amplitudes which is sufficient to drive s everal autonomous electrical devices. Such vibration-based energy harvester generates the most energy when the generator is excited at its resonance frequency. Simplest model to be start ed is of rectangular Aluminium cantilever beam with unimorph piezoelectric patch which is per fectly bonded to the substrate plate at the end. The resulting relative motion between the piez oelectric patch and the base produces stress on piezoelectric material,which is converte d into electrical power by virtue of direct piezoelectric effect. The ability of piezoelectric material of different thickness to generate voltage at different frequency is explained in this paper. Its capability to work over a range of frequency is predicted by use of ANSYS software. Th e solid model is design and analyzed using finite element software.
