摘要：

Quasiparticle band-structure calculations for semiconductors treat the exchange-correlation self-energy operator within the GW approximation. in this paper, a detailed study of the energy dependence of the self-energy due to dynamical screening is presented. Spectral functions for near-band-gap excitations in silicon and diamond are calculated and the quasiparticle peak and satellite structures are discussed.
