Research Description: Prof. Stephen W. Teitsworth's research centers on experimental, computational, and theoretical studies of deterministic and stochastic nonlinear electronic transport in nanoscale systems. Three particular areas of current interest are: 1) stochastic nonlinear electronic transport phenomena in semiconductor superlattices and tunnel diode arrays; 2) complex bifurcations associated with the deterministic dynamics of electronic transport in negative differential resistance systems; and 3) strategies for stabilizing negative differential resistance systems against the formation of space-charge waves.
