Electronic Structure Analyses of BN in Cubic and Hexagonal Phases

Abstract:

Article Preview

First principle calculations are performed on the structure, energy band gap, and dielectric properties of wurtzite and hexagonal BN by using a plane-wave pseudopotential method. It is found that h-BN has much narrower VB (valence band ) width and much sharper band edge than those of w-BN. And the N 2s states of the two phases of BN are dominant below 30.03 eV and the N 2p states are dominant in the range between −20.62 and 20.32 eV.
