Traditionally, progress in electronics has been driven by miniaturization. But as electronic devices approach the molecular scale, classical models for device behavior must be abandoned. To prepare for the next generation of
electronic devices, this class teaches the theory of current, voltage and
resistance from atoms up. To describe electrons at the nanoscale, we will begin
with an introduction to the principles of quantum mechanics, including
quantization, the wave-particle duality, wavefunctions and Schrödinger's
equation. Then we will consider the electronic properties of molecules, carbon
nanotubes and crystals, including energy band formation and the origin of
metals, insulators and semiconductors. Electron conduction will be taught
beginning with ballistic transport and concluding with a derivation of Ohm's
law. We will then compare ballistic to bulk MOSFETs. The class will conclude
with a discussion of possible fundamental limits to
computation.
