From: Electron mobility in semi-metal HgCdTe quantum wells: dependence on the well width
Dependence of the mobility on the electron concentration in the well. The QW width is 12 nm, the composition is Hg0.3Cd0.7Te/HgTe/Hg0.3Cd0.7Te. Curve 1 denotes the experimental data from Tkachov et al. (2011) for T = 4.2 K. Curve 2 shows our numerical data for T = 77 K. Concentration of residual charged impurities in the well is 1.14 × 1015 cm−3 (equal to 1.09 × 1010 cm−2)
