Intrinsic carrier concentration of Hg1−xCdxTe

Abstract
The intrinsic carrier concentration ni is measured for Hg1−xCdxTe with 0.205⩽x⩽0.22 and x=0.29 and 150<Tni=[1.265×1016T3/2(6+x)−3/2 E3/2G]{1+[1+22.72(6+x)3/2E−3/2G exp(EG/KT)]1/2}−1 (cm−3), where the band gap EG is given by EG(eV) =6.006×10−4T (1−1.89x)+1.948x−0.337.
