QUASI-PARTICLE BAND-STRUCTURE OF CDS

Quasiparticle band structure calculations which include the most impor tant cationic core states in the GW approximation of the self-energy o perator are reported for a prototype II-VI semiconductor. The most sal ient feature of our results for cubic CdS is the finding that the comp lete cationic N shell needs to be included in the pseudopotential and in the self-energy in order to obtain reasonable GW results in agreeme nt with experiment.
