摘要：

The one-electron excitation spectrum in BeTe, BeSe, and BeS bulk has been calculated within the ab initio GW approach. Band structures for interacting electrons are presented together with quasiparticle lifetimes and their inelastic mean free paths. The excitation-energy dependence of self-energy shifts and the rate of electronic dissipation processes is studied in detail.
