Abstract

A detailed study of the optical properties of semi-metallic compounds ScSb and YSb has been performed by means of ellipsometric method and first-principle TB-LMTO-ASA calculations. The calculated optical conductivity spectra are compared with experimental ones showing qualitative agreement. The low level of intra- and interband absorption in the infrared range of the spectrum is consistent with band calculations, which indicate a low density of electron states near the Fermi energy.
