Abstract
A self-consistent calculation procedure of the temperature dependences of the Gamma(6)-Gamma(8) energy gap (E(g)) and charge carrier mobilit y is proposed for undoped Hg1-xCdxTe real crystals (x similar to 0.1). It is shown that, in combination with methods of direct determination of E(g), this method may be used later for investigation of the elect ron density of states in the T-8 band degeneration region of zero-gap semiconductors. The mobility was calculated assuming a fourfold degene rate acceptor level in the conduction band with energy determined taki ng into account the features of the dielectric function under conditio ns of dynamic screening.
