V.; Yatsenko, A. V.; Sugak, D. Yu.; Solskii, I. M.The angular dependences of the linewidth of the 93Nb NMR spectrum central transition is experimentally investigated for the LiNbO3 crystal with congruent composition and for the samples with two various Mg concentrations. Due to the computer simulation of the NMR spectra according some scenario of Mg incorporation in the LNbO3 structure, it has been concluded that the defect complexes ( Li 2 MgL+i + V ) with the Li vacancies are realized when the Mg concentration is less then threshold.Item A concept of CSI-Li2B4O7 sandwich detector for simultaneous light charged particles and neutrons measurement(Видавництво національного університету “Львівська політехніка”, 2009) Borgensztajn, JoannaItem A New Application of Relaxor Ferroelectrics: Electrocaloric Cooling(2017-05-29) Suchaneck, G.; TU Dresden, Solid State Electronics Lab, 01062 Dresden, GermanyItem A new family of high Na+-ion conductivity solid electrolytes(Видавництво національного університету „Львівська політехніка”, 2009) Nalbandyan, V.

The dielectric response of polycrystalline ZnO thin films in the frequency domain was measured from 0.1 Hz - to 5 MHz frequencies with a small AC signal amplitude at different temperatures. Influence of the light on conductivity has been also investigated. A universal power law relation was brought into picture to explain the frequency dependence of AC conductivity. The temperature dependence of AC conductivity was analyzed in detail. The activation energy obtained from the temperature dependence of AC conductivity was attributed to the shallow trapcontrolled space charge conduction in the bulk of the sample.Item AFM study of Ni- and Cu-doped Li2B4O7 lass surface(Видавництво Львівської політехніки, 2012) Adamiv, V.

T.; Torun, M. K.; Yükselici, M. H.CdTe nanocrystals embedded in matrixes such as, glass, plastic and, aqueous solution have been investigated extensively due to their potential applications in nonlinear optical devices, biotechnology and medicine. When the size of bulk semiconductor is reduced to nanometer scales, the crystal gains new optical and electronic properties. Energy levels are quantized as in atoms and the energy difference between levels widens with the inverse of the size squared. CdTe nanocrystals were grown in glass by solid-state phase precipitation at the above glass transition temperature. A size dependent blue shift in the asymptotic absorption edge was observed in optical absorption spectra. The crystalline composition was studied by Resonant Raman spectroscopy. The width of the optical absorption tail at long wavelengths depends on the spread of electron energy levels within the structure, called the Urbach energy, which was calculated depending on size. We observe that the Urbach tail narrows as the surface to volume ratio of the nanocrystals decreases.Item Analysis and Design of Magneto-Optic Mach-Zehnder Isolator Made with a Magnetic Nanoparticles-Doped SiO2/ZrO2 Layer(2017-05-29) Bouras, Mounir; Hocini, Abdessalem; Department of Electronics, University of M’sila BP.166, Route Ichebilia, M’sila 28000, AlgeriaItem Analysis of Electromigration in MWO4 (M=Ca, Cd, Pb, Zn) Crystals and their Structural Defects(2017-05-29) Shevchuk, V.
