Abstract
We give a comprehensive study of carrier cooling and exciton formation in GaSe using femtosecond time-resolved photoluminescence. The initial subpicosecond cooling of hot carriers is due to the Fröhlich interaction with longitudinal optical E′ phonons and is followed by a slower cooling process dominated by the deformation potential interaction with nonpolar optical A′1 phonons. The subsequent formation of excitons and their spectral relaxation is studied at different carrier densities, detection energies and lattice temperatures.
