Paper Abstract

The refractive index and extinction coefficient of Hg1-xCdxTe prepared by polishing/etching are studied at liquid-nitrogen and room temperatures with null ellipsometric spectrum method over the visible light region, and reflectance is calculated from Fresnel reflectivity formula and show good agreement with experimental results from reflectivity spectra in the visible light region. Similar experiment is done for Hg1-xCdxTe sample prepared by anodic oxidation. The near infrared reflectivity spectra of Hg1-xCdxTe are measured at room temperature for three samples with different technological process: polishing, anodic oxidation and passivation with ZnS. The experimental results are compared and discussed.
