The <i>k·p</i> Interaction Calculations of Conduction Band and Valence Band of InN Materials

Abstract

Thek·pinteraction of the conduction band and valence band of InN materials was calculated in this paper. The nonparabolicity of the conduction band is more pronounced, because the conduction band feels stronger perturbation from the valence bands whenEgis smaller orEPis larger. The increase in absorption edge with increasing electron concentration was calculated by the dispersion relation. In the calculation, the conduction band renormalization effects due to electron interaction and electron-ionized impurity interaction are also taken into account. A good consistent picture is established in describing the conduction band of InN based on thek·pinteraction.
