Optical Properties of Heterostructures and Superlattices.

Abstract

The investigation of the optical properties of heterostructures and quantum wells in semiconductors has produced a number of results of basic and practical importance. Experimental and theoretical studies of luminescence of a single quantum well under laser excitation established exciton transport as the mechanism for providing the electron-hole pairs which recombine within the well. This contradicts previous models of electron hole transport into quantum wells. The significance to heterojunction and quantum well lasers is obviously relevant. Contents: Exciton Transport in Optically Excited Al(x)Ga(1-x)As-GaAs Single Quantum Well; A New Quantum State in Multiple Quantum Well Structures; and High-density Excitonic State in Two-dimensional Multiquantum Wells. Keywords: Exciton; Luminescence; Magneto-optics; Semiconductor lasers.
