Структура и транспортные свойства ниобатов и эрбатов висмута

Abstract

The solid solutions with general formula have been prepared by solid state synthesis. Analysis of the powder X-ray diffraction data has shown that the samples crystallize in cubic space group Fm3m. Microscopic research were performed using a REM. Electrical conductivity was studied by impedance spectroscopy. The electrical conductivity of doped samples exceeds the matrix value and increases with increasing concentration of dopant.
