Abstract
The optical absorption edges in gettered and ungettered Hg0.8Cd0.2Te alloys have been investigated. It is found that the absorption edge was moved to the short wave direction after the sample was gettered. The change of absorption edge has also been found in Hg0.8Cd0.2Te containing different mercury concentrations. Possible explanations for the phenomena are discussed.Keywords
