Research Synopsis
Current research focus is the fabrication of nanoscale electronic/optical/magnetic devices and sensors on a scale of sub-nanometers to hundreds of nanometers. This includes
  • development of wafer-scale methods to place individual nanoscale building blocks (such as nanoparticles, nanowires, carbon nanotubes, DNA, proteins, etc) on exact substrate locations
  • study and fabrication of single electron devices on a wafer scale within the framework of CMOS fabrication technology
  • development of ultra-sensitive biological/chemical sensors that can detect single molecules (DNA, proteins, etc) on portable chips.

This is an introductory and intermediate level course for materials scientists, physicist, chemist, and electrical engineers. This course is comprised of two parts: (1) Solid State Physics  (2) Thermodynamics and Statistical Mechanics. Solid State Physics in this course is mainly the physics of crystals. We will cover the crystal structures of solids, reciprocal lattices, phonons, electronic energy states of solids, optical properties of solids, metals, and semiconductors. For Thermodynamics & Statistical Mechanics, we will study the basic concepts of classical thermodynamics, the introductory statistical mechanics, and the relationship between them. Basic Quantum Mechanics will be introduced where appropriate.
