Elementary energy bands concept, band structure, and peculiarities of bonding in β-InSe crystal

Autor: N. K. Tovstyuk, K. E. Glukhov

Publikováno v: physica status solidi (b). 247:318-324

The elementary energy bands concept together with the analysis of the Davydov-like splitting were applied for the first time for investigation of energy band structure and spatial electron density distribution in hexagonal crystals. This approach was

Screening effects through electron-electron interaction in the crystal structures of an intermediate dimension

Autor: N. K. Tovstyuk, Ivan Franko

Publikováno v: Semiconductor physics, quantum electronics and optoelectronics. 8:32-36

In the paper studied are polarization properties of an electron subsystem in the structures of intermediate dimension, particularly, in the quasi-two-dimensional structures depending on the degree of quasi-two-dimensionality. These investigations wer

KINETICS AND PHOTOELECTRET PHENOMENA OF LAYER SEMICONDUCTOR LASER INTERCALATED BY NICKEL

Autor: N. K. Tovstyuk, V. L. Fomenko, I. I. Grygorchak, P. Y. Stakhira

Publikováno v: International Journal of Modern Physics B. 22:709-717

The mechanisms of the photoelectretic effect appearing on Ni intercalation GaSe were studied. The presence of the photoelectretic effect for such an object of investigation can be explained by the estimation that in Ni intercalated GaSe , the nonequi
