The influence of low-temperature annealing on properties of heterostructures p-HgCdTe grown by molecular-beam epitaxy

In heterostructures p-HgCdTe changes of density and mobility of major carriers, mobility and lifetime of minor carriers were investigated after some contacts with water and annealing at 80°C. The obtained dependencies for samples from various heterostructures have a strong difference. For some heterostructures the density of major carriers and lifetime of minor carriers sharply increased after such treatments.
