A study of the photoluminescence of (In As) „ (GaAs) m superlattices reveals that its intensity may be substantially higher than that of GaAs in the barriers. A mechanism of carrier trapping in quantum wells is proposed. The transition from the case of noninteracting quantum wells to superlattices as the barrier thickness is varied is analyzed. A polarized photoluminescence of (In As) „ (GaAs) ,„ superlattices under stress has been observed.
