The metal-insulator transition in semiconductors
Fedor V. Prigara
The temperature dependence of the number density of elementary excitations in a semiconductor with account for the temperature dependence of the band gap is obtained. A local latti…
Effect of strong electric fields on ferroelectric and metal-insulator transitions
Fedor V. Prigara
It is shown that a sufficiently strong external electric field causes a decrease in the transition temperature of ferroelectric, antiferroelectric, and metal-insulator transitions.…
The dissolution of the vacancy gas and grain boundary diffusion in crystalline solids
Fedor V. Prigara
Based on the formula for the number density of vacancies in a solid under the stress or tension, the model of grain boundary diffusion in crystalline solids is developed. We obtain…
The dissolution of the vacancy gas in solids and high pressure phase transitions
Fedor V. Prigara
The formula for the number density of vacancies in a solid under pressure is obtained. The mean number density of vacancies in a solid under stress or tension is also estimated. Th…
