Hg1−xCdxTe/Hg1−xZnxTe superlattices with constant Hg content

Abstract

Hg1−xCdxTe/Hg1−xZnxTe superlattices with constant Hg content have been grown by molecular beam epitaxy for x between 0.22 and 0.4. Films grown at 180 °C show x-ray satellite peaks to the fourteenth order. An annealing study conducted between 185 and 225 °C shows enhanced stability compared to HgTe/CdTe superlattices.
