Determination of polarization charge density on interface of AlGaN/GaN heterostructure by electroreflectance

Wu, Chia-Chun 10 July 2006 (has links)
Electroreflectance spectra of AlGaN/GaN heteostructure were measured for various biased voltage (Vbias). There are Franz-Keldysh oscillations (FKOs) exhibiting above band gap of AlGaN, and strength of electric field of AlGaN (FAlGaN) can be evaluated from periods of the FKOs.
