Spectroscopic and Structural Aspects of Femtosecond Dynamics of Reflectivity of AIGaAs/GaAs Superlattices

Abstract

In this paper, we present results of studying dynamics of nondegenerate (two-colour) photoreflection of the AlGaAs/GaAs superlattices. These results show unique potential of these methods (i) for identification of sources of inhomogeneous broadening of optically-active 2D excitons, (ii) for analysis of fine structure of excitonic states hidden in inhomogeneous broadening, and (iii) for determination of spectral distribution of probability of radiative annihilation of 2D excitons and its relation to structural disorder.
