Research Description: 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.
