Abstract
A detailed description of excitonic spectra in semiconductor nanostructures needs to take into account roughness-induced disorder. Results are presented for a kinetic equation, which is formulated in terms of disorder eigenstates and includes phonon relaxation and radiative exciton, decay. Depending on the excitation scheme, the solutions describe photoluminescence, photoluminescence excitation spectroscopy, or absorption. Their dependence on time, temperature, disorder strength, and spatial resolution can be studied. Spatially resolved spectra turn out to be particularly interesting: Their autocorrelation contains information on the spatial extension of the wave functions, which is otherwise inaccessible.
