Stephen W. Teitsworth, Associate Professor of Physics

Stephen W. Teitsworth

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.

Prof. Stephen W. Teitsworth's current research centers on electronic transport and optoelectronic processes in semiconductor microstructures and nanostructures. Three areas of particular interest are: 1) nonlinear electronic transport in semiconductor superlattices; 2) theoretical and experimental studies of chaotic dynamics associated with nonlinear space charge waves in patterned and bulk semiconductors; 3) optical properties of semiconductor quantum wells, especially photon-plasmon effects in structures that incorporate metallic nanoarrays.
