摘要：

Defects in two chalcopyrite semiconductors AgGaS2 and CuGaS2 have been studied by a combination of several optical techniques including absorption, emission, Raman scattering and their excitation spectroscopies. From these measurements we have determined the binding energies of both shallow and deep donors and accepters in the two materials.
