Sm. Komirenko, FEATURES OF THE TRANSPORT PHENOMENA AND TEMPERATURE-DEPENDENCE OF THEGAMMA-6-GAMMA-8 ENERGY-GAP IN UNDOPED ZERO-GAP N-(CD, HG)TE CRYSTALS, Semiconductor science and technology, 9(1), 1994, pp. 19-25
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.
