Abstract

The refractive index spectra of Ga_xIn_1-xAs_ySb_1-y MBE epitaxy layers above, near and below the band gap were studied by room-temperature infrared ellipsometric spectroscopy with different compositions. The band-gaps were determined by refractive enhancement. It was found that the band gap energy changes approximately linearly as a function of composition between x = 0. 2∼0. 3.
