Computational Nanoelectronics:
Towards Design, Analysis, Synthesis, and Fundamental Limits
Nanotechnology has received
a lot of public attention since President Clinton announced the National
Nanotechnology Initiative. New
approaches to applications in electronics, materials, medicine, biology and a
variety of other areas will be developed in this new multi-disciplinary
field. Notably, nanotechnology has
already arrived in practical devices in the world of semiconductor
electronics. Wave-like properties of
electrons modify the functional device behavior once spatial variations in
structures reach length scales of a few tens of nanometers. The modeling and simulation of such devices
now deviates strongly from classical approaches: it must be fundamentally
quantum mechanical. While standard
technologies require extensive simulation tools for design, analysis and
characterization, few such tools exist for nanoelectronic
devices. This seminar will review the
development of a comprehensive nanoelectronic modeling
tool (NEMO), its algorithm and theory development, its utilization of low cost
clusters for high performance computing, and its application to high-speed
electronics, IR detectors and lasers.
Device synthesis from performance specifications and device
characterization via device simulation will be demonstrated.
