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.
