Abstract :
This paper proposes different ways of the capture efficiency increase without in-quantum-well-eigenstates spectrum perturbation based on the analysis which uses an original self-consistent methodology of the potential profile and eigenstates spectrum computing. The carrier capture efficiency for different structures and different optimization methods is computed. Finally, the laws of the semiconductor alloy composition are determined, which provide the lattice-matched separate confinement-area and required potential profiles.
