Аннотация

Congruent LiNbO3 (LN) and LiNbO3+MgO (MLN) crystals belong to the materials with high initial concentration of antisite defects. These defects are charged positively with respect to the lattice, act as deep electron traps and play very important role in electronic processes. Introduction of MgO-impurity in LiNbO3 change the concentration of these states and alteration in conductivity is expected. The conductivity of samples was studied in relation with MgO content. Information about spectrum of localized states was obtained by optical measurements and method of cathodoluminescence. Observed luminescence has noninertial character and their spectrum shifts to the realm of low energies with grows in MgO content. The data demonstrate essential change in density of states associated with antisite defects. Analysis shows that at low temperature the most probable mechanism of charge-transfer in LN and MLN crystals is hopping of small polarons.
