Optical Properties of Epitaxial Films of CdxHg1−xTe

Abstract
Epitaxial crystal films of alloys of CdTe and HgTe and BaF2 substrates have been produced by a flash‐evaporation technique. The energies of several interband electronic transitions have been measured and found to vary linearly with composition. Arguments are presented that this method produces single‐crystal alloy films of accurately predetermined composition.
