Abstract
The optical constants of HgTe and HgSe are determined in the photon energy region 1.7∼3.5 eV from ellipsometric measurements at room temperature. The structures associated with the E 1 and E 1+Δ 1 band edges are found in the extinction coefficient spectra at energy values nearly coincident with the data of the normal incidence reflectivity for both materials. Tentative surface film corrections are made at several photon energies.Keywords
