title = "Temperature-dependent time-resolved photoluminescence study of monocrystalline CdTe/MgCdTe double heterostructures with low defect density",
abstract = "Confocal photoluminescence scans of monocrystalline CdTe/MgCdTe double heterostructures epitaxially grown on lattice-matched InSb substrates reveal very low twin defect density, below 1 × 105 cm-2. Room-temperature Shockley-Read-Hall (SRH) lifetimes of these samples are determined in the range of 35 ns to 86 ns using time-resolved photoluminescence (TRPL) measurements. Temperature-dependent TRPL measurements show that the carrier lifetime reaches a peak of 910 ns at 200 K. Excitation-dependent PL measurements reveal the radiative recombination coefficient of CdTe to be 4.3 × 10-9 cm3·s-1.",
