Abstract
We have carried out a study and identified that MBE HgCdTe growth-indu ced void defects are detrimental to long wavelength infrared photodiod e performance. These defects were induced during nucleation by having surface growth conditions deficient in Hg. Precise control and reprodu cibility of the CdZnTe surface temperature and beam lures are required to minimize such defects. Device quality material with void defect co ncentration values in the low 10(2) cm(-2) range were demonstrated.
