Abstract
The results of MBE growth and annealing of p-type HgCdTe are described in the paper. It is found that the surface morphology is sensitive to the growth temperature. HgCdTe epilayers showed excellent lateral uni formity in x-values as well as in thickness, relative deviations for x and thickness over a 2 in. wafer were found to be 0.18% and 2.19%, re spectively. The hole concentrations in a range of (1-2) x 10(16) cm(-3 ) with hole mobilities higher than 600 cm(2) V(-1)s(-1) were obtained by p-annealing. MBE grown p-HgCdTe epilayers were successfully incorpo rated into 32 x 32 focal plane arrays detectors.
