Semiconductor Spectroscopy Laboratory
Research in the Semiconductor Spectroscopy Laboratory has focussed on the characterization and modeling of advanced compound semiconductor materials and devices for optoelectronic applications. Characterization techniques in the SSL include photoluminescence, photoluminescence excitation, photoreflectance, electroreflectance and photocurrent spectroscopies, and modeling efforts include band-structure calculations for heterostructures, quantum well and superlattice
optical properties and optoelectronic device models. The SSL is directed by Professor Neal
G. Anderson.
