Momentum matrix elements of quantum dot structures with and without applied electric field

Abstract EN

Diagonal and off-diagonal momentum matrix elements of quantum dot (QD)structures with and without applied electric field were modeled for the structurelayers; QD layer and wetting layer (WL).

Orthogonal zed plane-wave (OPW) wasconsidered for in-plane WL states.

While there is a definite size gives maxima for off-diagonal elements, the ondiagonalelements under applied field increases with size.

Some of on-diagonalelements increase with field while some other decreases.
