Ion Beam Nanostructuring of HgCdTe Ternary Compound

open access: yesNanoscale Research Letters, 2017
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

open access: yesJournal of Applied Physics
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 ...

Ultrafast photoconductivity dynamics in narrow-gap HgCdTe films

open access: yesAPL Materials
Mercury cadmium telluride (Hg1−xCdxTe or MCT) is the premier material for infrared detection. However, despite its importance, studies exploring the ultrafast photoresponse in this semiconductor alloy are limited.
