HgCdTe Surface Study Program

Abstract

The cleaved <110> surface of HgCdTe has been investigated using photoemission spectroscopy (PS) and Auger electron spectroscopy (AES). The results have been compared to CdTe. States due to Hg in the lattice were identified. The cleaved surface of p-type solid-state recrystallized (SSR) HgCdTe is seen to be enriched in Hg and shows no evidence of out-diffusion in a high vacuum (10 to the -10th power torr). The surface shows no adsorption of dry molecular oxygen. Exposure to excited oxygen results in growth of Te-oxide. AES on epitaxial HgCdTe before and after ion bombardment indicates that bombardment significantly perturbs the composition of the surface region.
