Extended band anti-crossing model for dilute bismides

Bandstructure properties of dilute bismide bulk systems are calculated using density functional theory. An extended band anti-crossing model is introduced to fit the obtained results. Using these as inputs for a fully microscopic many-body theory, absorption and photoluminescence spectra are compute...

Zusammenfassung:	Bandstructure properties of dilute bismide bulk systems are calculated using density functional theory. An extended band anti-crossing model is introduced to fit the obtained results. Using these as inputs for a fully microscopic many-body theory, absorption and photoluminescence spectra are computed for bulk and quantum-well systems. Comparison to experimental results identifies the applicability range of the new anti-crossing model.
