A sharp line transition at 1.51385 eV has been observed in the photoluminescence spectra of an epitaxially grown crystal of GaAs. A Si3N4 cap was applied by plasma deposition and the crystal was then annealed at 850 °C for 15 min. The sharp emission

The first observation of six sharp photoluminescence lines with energies less than the energies of the lines associated with a radiative recombination of a single exciton bound to a neutral acceptor in high purity epilayers of GaAs at liquid helium t

The exciton energy spectrum in GaAs has been studied by photoluminescence and reflection. The photoluminescence was excited using a krypton laser (6471 \AA{}). We observed for the first time the spectra for the excited states of the free exciton in G

We report the first observation of three different residual donors in undoped high purity vapor phase epitaxial GaAs using the high resolution photoluminescence spectroscopy technique at temperatures ∼ 2 K. The binding energies of these shallow don

Magneto-optical analysis of prominent photoluminescence lines from GaAs FET structures has been performed. Fifteen samples were investigated. Each consisted of a sulfur doped active layer on a high resistivity buffer layer (both epitaxially grown fil

A comparison between the ultraviolet-reflectivity spectrum and the characteristic energy-loss spectrum of ZnO has been carried out. Reflectivity measurements made over an energy range of band gap to 22 eV yielded a spectrum with structure at 3.34, 5.
