Popis: By means of electrical and magnetic investigation of Yb-doped CdTe crystals, the following was established: (1) Additional shallow donors and paramagnetic centers are not introduced into the doping process; the hole conductivity of doped crystals is controlled by A-centers; their ionization energy depends on Yb impurity concentration (C) according to the law E A = (0.15 + 2.4 × 10 −11 C −1 2 ) eV; (2) It is supposed that Yb impurity deforms the lattice so that the components of the complex A-center move away one from another when the concentration (C) increases; and EA increases accordingly.
