Raman Spectroscopy and Photoluminescence Laboratory

 

 

The Laboratory of Raman Spectrocopy and Photoluminescence is focused on the study of the optical properties of semiconductor materials. Among others, we have carried out Raman scattering studies on a variety of III-V compound systems such as GaN, InN, InGaN, InAs/GaAs, InGaAs, InP, AlGaSb, InAsSb, GaSb, GaAsN, as well as on ZnO, a II-VI wide band gap material which is intensively being investigated because of its potential applications in transparent electronics and in blue and UV light emitters.
