Excitonic properties of ZnS quantum wells in ZnMgS

Abstract:

The excitonic properties of cubic ZnS quantum wells in ZnMgS are studied by reflectivity and magneto-optics. A remarkable improvement in the quality of the samples grown by MBE on Gal? substrates has allowed the observation of heavy and light hole exciton transitions with values for the FWHM as narrow as 5 meV The 2s state of the heavy hole exciton is identified and exciton binding energies as high as 55 meV are deduced, indicating that for quantum wells narrower than 3.5 nm the exciton-LO ph...
