Electronic Band-Edge Structure, Effective Masses, and Optical Absorption of Si1-¡xGex Using an Extended FPLAPW/VCA/LDA+U Computational Method

Electronic band-edge structure and optical properties of Si1¡xGex are investigated theoretically emloying afull-potential linearized augmented plane wave (FPLAPW) method. The exchange-correlation potential in thelocal density approximation (LDA) is corrected by an on-site Coulomb potential (i.e., wi...
