Abstract
The electronic conductivity of Sr(3-3x)La(2x)square(x)(VO4)(2) solid soluti ons was measured at oxygen pressures from 10(-13) to 10(5) Pa and temperatu res from 1070 to 1270 K, and their band gap was determined as a function of composition. The activation energy (similar or equal to 2.85 eV) and entha lpies of electron generation (similar or equal to 4.2 eV) and migration (si milar or equal to 0.75 eV) were determined. A correlation between the band gap and electronic conductivity of the solid solutions was revealed.
