Abstract
The possibility of significant lowering of the interband lasing threshold in laser structures of the mid-infrared region based on HgCdTe with HgTe quantum wells by doping with donors, which introduce δ layers near quantum wells, is proposed and analyzed. It is shown that at an optimum surface donor concentration in the δ layer of 4 × 1010 cm–2 and an operating temperature of >40 K, the lasing threshold at a wavelength of 20 μm can be lowered more than twofold.
