Self-Consistent Treatment of V-Groove Quantum Wire Band Structure in no Parabolic Approximation

Abstract

The self-consistent nonparabolic calculation of a V-groove-quantum-wire (VQWR) band structure is presented. A comparison with the parabolic flat-band model of VQWR shows that both, the self-consistency and the nonparabolicity shift subband edges, in some cases even in the opposite directions. These shifts indicate that for an accurate description of intersubband absorption, both effects have to be taken into the account.
