Paper Abstract

Optical anisotropy in the refractive index and in the absorption coefficient of GaTe has been studied in the layer plane. The refractive index has been determined in the wavelength range from 0.7 to 25 micrometer and the absorption coefficient in the range of energies from 1.6 to 2 eV. The refractive index dispersion is interpreted through Phillips-Van Vechten and Lorent- Drude models, yielding values of the Penn gap of Epg (perpendicular b) equals 3.37 eV and Epg (parallel b) equals 3.58 eV. The absorption coefficient has been found to be very slightly anisotropic, which is shown to be coherent with the Se pz-like character of the valence band.
