Abstract

We find that in SiSiGe three-dimensional multilayer nanostructures, photoluminescence intensity as a function of temperature depends on the excitation intensity. The experimental results are explained using a model where electron-hole separation and nonradiative recombination is controlled by a competition between hole tunneling and thermally activated hole diffusion over the valence band energy barriers at SiSiGe heterointerfaces.
