Autor: Horon, B. I., Kushnir, O. S., Shchepanskyi, P. A., Stadnyk, V. Yo.

Publikováno v: Condensed Matter Physics, 2022, vol. 25, No. 4, 43704

We study the temperature dependence of dielectric permittivity along the polar axis for ferroelectric ammonium fluoroberyllate (AFB) crystal in the vicinity of its phase transition points. The experimental data within incommensurately modulated phase

Heterostructures manufactured by annealing of InSe monocrystals in sulfur vapor

Autor: Kovalyuk Z. D., Kushnir O. I., Sidor O. M., Netyaga V. V.

Publikováno v: Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, Iss 1, Pp 61-62 (2009)

InS/InSe heterostructures were created by a long-term (during 120 h) thermal processing of InSe monocrystals in sulfur vapor. Investigations of electrical and photoelectric properties of structures manufactured by this method showed essential advanta

Crystal Optical Properties of Inhomogeneous Plates and the Problems of Polarization Tomography of Photoelastic Materials

Autor: Kushnir, O., Nek, P., Vlokh, R., Kukhtarev, N.

Publikováno v: Ukr. J. Phys. Opt. 2005 6 87-93

Using the Jones matrix formalism, crystal optical properties of inhomogeneous material consisting of a pile of weakly birefringent plates are analysed in relation to the cell model adopted in polarization tomography of 3D dielectric tensor field in p
