ABSTRACT
Gold-doped Hg[SUB1-x]Cd[SUBx]Te samples of x = 0.2067 (in the very-long-wavelength infrared spectral band, with cutoff wavelengths ∼ 13.2 μm at 77 K) were prepared by tellurium-melt liquid-phase epitaxy. The samples were doped with indium to ∼ 2 × 10[SUP14] cm[SUP-3] and gold to ∼ 7 × 10[SUP15] cm[SUP-3], and were characterized by secondary ion mass spectroscopy, Hall measurements, and minority carrier lifetime measurements. State-of-the-art minority carrier lifetime of ∼ 0.82 μs was obtained.
