Research Interests:

Prof. Stephen W. Teitsworth's current research centers on the theoretical and experimental studies of nonlinear electronic transport in semiconductor superlattices and related structures. Three areas of particular interest are: 1) stochastic nonlinear electronic transport properties of semiconductor superlattices and tunnel diode arrays; 2) chaotic dynamics associated with nonlinear space charge waves in patterned and bulk semiconductors; 3) strategies for stabilizing negative differential resistance systems against the formation of space-charge waves.
