E. Buzaneva et al., XPS STUDY OF NONSTOICHIOMETRY FOR CHALCOPYRITE CRYSTAL, Journal of electron spectroscopy and related phenomena, 68, 1994, pp. 727-730
Electronic structure and composition of the needle-shaped CdSi(x)P(y)
crystal native growth surface is investigated using XPS for the purpos
e to study nature of nonstoichiometry for chalcopyrite crystal. We pro
pose to use variation in the P 2p and Cd 3d electron binding energies
for identification of substitutional and exchange defects for native g
rowth surface of chalcopyrite crystal.
