AbstraktAbstract

The luminescence induced by alpha particles in GaAs/Al0.35Ga0.65As multiple quantum well (MQW) semiconductor was-detected and investigated. The luminescence was observed at liquid nitrogen and at room temperatures as light flashes induced by individual alpha -particles. The M&W samples studied, in addition, were investigated using standard photoluminescence method to show that ct-particle created flashes are associated with the radiative decay of 2D excitons in quantum wells. Since the number of detected light quanta in a flash is critical, a discussion of the collection efficiency of photons created by a single alpha -particle is presented.
