  • Nanoelectronics Researcher Receives AFOSR Grant
Apr 2008
Eui-Hyeok Yang, PhD, has received a three-year grant from the Air Force Office of Scientific Research (AFOSR) under the Physics and Electronics Directorate for nanoelectronics research based on carbon nanotube (CNT) quantum dots. The specific amount of the grant was not disclosed. Yang, associate professor in the Department of Mechanical Engineering at Stevens Institute of Technology in Hoboken, N.J., will serve as the principle investigator on the project, titled "Ultra-High-Speed Single Electron Memory Devices Based on Carbon Nanotube Quantum Dots." Yang and the research team will exploit novel in-plane CNT structures and investigate their quantized energy properties for use in future high-speed, low-power electronics. “New analog and digital electronic devices based on single-electron behavior are considered strong candidates to replace silicon transistors in future ultradense, low-power, high-speed electronics," Yang said. "Carbon nanotubes possess enormous potential to facilitate superior single electron transport functionality due to unique properties such as high electron charging energy, short electron traversal time and high thermal conductivity. Despite the promise of vastly superior performance of CNT structures, several fundamental issues in the fabrication and characterization need to be researched and resolved for single-electron memory applications.” His project team consists of two other Stevens faculty members, professor Frank Fisher of Mechanical Engineering and Stefan Strauf, assistant professor in the Physics and Engineering Physics department. Dan Choi, a professor at the University of Idaho, will also participate.

A physical variable that is proportionally similar to another variable over a specified range. An analog recording contains data that is similar to the source.
A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number is 1/2. Its positive counterpart is called a positron, and possesses the same characteristics, except for the reversal of the charge.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
quantum dots
Also known as QDs. Nanocrystals of semiconductor materials that fluoresce when excited by external light sources, primarily in narrow visible and near-infrared regions; they are commonly used as alternatives to organic dyes.
