Title: Effect of sulfur doping on optical anisotropy of CdSiAs{sub 2}

Abstract

Polarization dependent photoluminescence and photocurrent measurements were carried out on undoped and sulfur doped single crystals of CdSiAs{sub 2}. For undoped crystal the interband transition {ital A} shows a 40 meV blueshift under perpendicular light polarization with respect to the parallel one. This shift is about twice as large for sulfur doped crystal. A pronounced photoabsorption band at 1.53 eV, related to the sulfur donor, is observed in the low temperature photocurrent spectrum. A significant enhancement of the optical anisotropy of donor-acceptor transition is seen in the low temperature photoluminescence spectra of CdSiAs{sub 2} doped with sulfur. {copyright} {ital 1996 American Institute of Physics.}
