Excitonic properties of high-quality ZnS layers grown by low-pressure metal-organic vapor-phase epitaxy have been investigated using photoluminescence and absorption spectroscopy. Comparison with theoretical models has provided accurate information on eigenstates, broadening, strain, and temperature dependence of heavy-hole, light-hole, and split-off-band exciton transitions. Finally, radiative recombination due to inelastic exciton-polariton scattering is shown under strong injection rates.

Abstract
Excitonic properties of high-quality ZnS layers grown by low-pressure metal-organic vapor-phase epitaxy have been investigated using photoluminescence and absorption spectroscopy. Comparison with theoretical models has provided accurate information on eigenstates, broadening, strain, and temperature dependence of heavy-hole, light-hole, and split-off-band exciton transitions. Finally, radiative recombination due to inelastic exciton-polariton scattering is shown under strong injection rates.File in questo prodotto:
