Abstract：
A new measurement method of characteristic lifetime of positron annihilation in mercury cadmium telluride (MCT) in thermoequilibrium with mercury vapor was proposed. A result of τ _bthe annihilation lifetime of positrons in bulk state in HgCdTe, being 277±lps,and τ _b, the lifetime of positrons trapped in mercury vacancies,being 306±2ps was obtained. The result was discussed and compared with that from other methods.
- positron annihilation,
- defects in mercury cadmium telluride semiconductors,
- mercury vacancies
