Qısa məlumat

The electrical and thermal properties of extruded samples of Bi85Sb15 < Te > modified with ZrO2 were investigated depending on the dose of gamma radiation in the temperature range similar to 80 divided by 300 K and magnetic field strength (H) similar to 74 x 10(4) A/m. It was found that an increase in the mobility in the irradiated modified Bi85Sb15 < Te > is associated with the radiation introduction of acceptor (negatively charged) centers, which at low doses are generated mainly in the regions of the efficiency of impurity scattering of charge carriers and partially neutralized centers and, accordingly, to a certain increase in the mobility. In the extruded modified samples of the Bi85Sb15 solid solution, irradiation with gamma quanta results not only in the generation of radiation defects (RDs) (centers), but also accompanied by their rearrangement. This causes a change in the spectrum of localized states and the electron scattering process, which leads to corresponding changes in the presented electrical and thermal parameters.
