Polarization Effects in Optical Properties of GaSe Crystal Bulk and Surfaces

Abstract

This report results from a contract tasking TUBITAK, Marmara Research Center as follows: The contractor will investigate the anisotropy of the optical properties of quasi two-dimensional crystals, specifically of GaSe, using IR absorption and exciton photoluminescence spectroscopy over a wide frequency range. The results obtained will be used to determine the mechanism of free carrier scattering and its anisotropy; to identify the nature of peaks observed in the anisotropy of IR absorption spectra; and to construct the equations describing the spectral dependence of the absorption coefficients for two polarization in the spectral range of 1-25 mm.
