Effect of charge ordering on superconductivity in high-temperature superconductors
Fedor V. Prigara
It is shown that charge ordering in layered crystalline metals causes an increase in the normal state energy of the conducting layers. If this increase in the energy exceeds the di…

The metal-insulator transition and lattice distortion in semiconductors
Fedor V. Prigara
A relation between the energy of an elementary `insulating' excitation corresponding to the metal-insulator transition and the bandgap width in a semiconductor is obtained. An effe…

Charge gap, lattice distortion, and ferroelastic fluctuations in high-temperature superconductors
Fedor V. Prigara
It is shown that a ferroelastic lattice distortion is associated with the superconducting transition both in low- and high-temperature superconductors. In layered tetragonal superc…
