Photoinduced Phenomena in Sulphur Crystals and Films
Autor: I. V. Kityk, O. G. Yablonovska, Ya. O. Dovgii
Publikováno v: Acta Physica Polonica A. 81:405-408
The irradiation of sulphur crystals and films with ultraviolet light induces the change of transmission in the visible part of spectra. It was found that these phenomena exist only at low temperatures (4.2-50 K). The behaviour of optical transparency

Autor: M. K. Zamorskii, I.V. Kityk, A. V. Franiv, A. S. Krochuk, M. I. Kolinko, Ya. O. Dovgii
Publikováno v: physica status solidi (b). 167:637-646
For the first time self-consistent band-structure calculations of TlI single crystals (space group O) are performed using nonlocal pseudopotentials. The method is described briefly. The contributions of the different band states to the charge density

Band Structure and Nonlinear Optical Susceptibilities of Proustite (Ag3AsS3)
Autor: Ya. O. Dovgii, I.V. Kityk
Publikováno v: physica status solidi (b). 166:395-402
Theoretical and experimental investigations are made of the band structure of proustite (Ag3AsS3). The calculation is performed using the tight-binding method. As scale factors in the corresponding secular equation the experimental results of VUV-ref

Sign inversion of the rotatory power and topology of the surface of gyration of αNiSO4·6H2O
Autor: Ya. O. Dovgii, I. G. Man’kovskaya
Publikováno v: Physics of the Solid State. 40:1460-1461
The sign inversion point of the rotatory power of the gyrotropic crystals α-NiSO4·6H2O (λl=503 nm at 300 K) has been established. The topology of the gyration surface varies greatly in the vicinity of λl. We have demonstrated the possibility of u
