Ion Beam Nanostructuring of HgCdTe Ternary Compound
Systematic study of mercury cadmium telluride thin films subjected to the ion beam bombardment was carried out. The evolution of surface morphology of (111) Hg1 − x Cd x Te (x ~ 0.223) epilayers due to 100 keV B+ and Ag+ ion irradiation was studied by ...

The electron affinity of HgCdTe
An accurate formula for electron affinity is necessary for the correct modeling of Hg1−xCdxTe devices. We show that the most commonly used formula is inaccurate. We construct a generalized equation for the electron affinity based on certain properties of the HgCdTe alloy system and select the experimental values to insert, producing a recommended ...
