A brief introduction to the physics of semiconductors and semiconductor devices, culminating in an understanding of the structure of integrated circuits. Topics include a description of currently available integrated circuits for analog and digital applications and their use in modern electronic instrumentation. Weekly laboratory exercises with integrated circuits.
A thorough review of particle dynamics, followed by the development of Lagrange’s and Hamilton’s equations and their applications to rigid body motion and the oscillations of coupled systems.
Ph.D. in experimental Solid State Physics from Brown University.
M.Sc. in Physics from University of Massachusetts, Amherst.
B.S. in Physics from University of Massachusetts, Amherst.
High magnetic field effects and low temperature phenomena associated with electronic systems of restricted dimensionalities, including magneto-transport, Integer and Fractional Quantum Hall Effect, resonant tunneling structures, and properties of novel semiconductor systems.
