Nanoscale devices for electronics and optics

Professor Leburton has been investigating nanoscale devices for electronics and optics. His theoretical studies involve sophisticated quantum mechanics to describe the behavior of confined electrons in interaction with the material environment. He has recently developed advanced computer models for predicting the operation of quantum dot flash-memory silicon transistors, and quantum dot mid- and far-infrared lasers. During his Center appointment, he will focus on the general electronic properties of quantum dots resonant tunneling devices and visible lasers. He hopes to elucidate the mechanism of fast carrier relaxation in self-assembled InAs/GaAs quantum dots for the dynamical response of quantum dot-based lasers. Nanotechnology is an emerging field in the science and engineering of artificial materials. With the continuous trend toward miniaturization of electronic and opto-electronic components, nanostructures containing just a few electrons such as semiconductor quantum dots, become increasingly important for the fabrication of high performances and high functionality devices and systems. Applications of quantum dots in ultra-high density memories, high performance lasers and optical detectors have been envisioned. However, design and fabrication of quantum dot-based devices cannot be made without in-depth understanding of their basic properties and the physical parameters, which influence their characteristics.
