General one-dimensional computation formula and application to donorbinding energy in GaAs-Ga1-xAlxAs superlattice,

摘要

Abstract: In this paper, the general formula was found for one- dimensional computation of GaAs-Ga$-1-x$/Al$-x$/As superlattice or quantum well. The formula can be used to calculate donor binding energy in external field using the effective-mass approximation. The effect of superlattice structure and different external fields were expressed as potential energy item V vector (r) in Hamiltonian. The results were of universal significance in a certain sense and application prospects for developing new material. !8
