Abstract:

Femtosecond transient transmission spectroscopy has been used to study the generation and thermalisation of hot photoexcited electrons and holes in semiconductors. Work on bulk AlxGa1-xAs has been extended to include a detailed numerical model of carrier thermalisation and cooling, which allows for dynamic screening of carrier-phonon interactions. This model shows excellent agreement with experimentally observed effects such as hole burning, single LO-phonon emission by electrons and two-temperature behaviour of electrons and holes at early times (<10 ps). Hole burning measurements have also been made on type-I GaAs/AlAs superlattices, where the density dependence of the transient transmission spectra has been investigated. © 1992.
