Analysis of self-trapped hole mobility in alkali halides and metal halides
(Elsevier B.V., 2017)
The small radius hole polarons (self-trapped holes (STH) known also as the Vk centers) are very common color centers observed in numerous alkali halides and alkaline-earth halides. Their mobility controls the rate of ...
Rakstura audzināšanas ietvars skolām
(University of Birmingham, Jubilee Centre for Character and Virtues, 2017)
“Rakstura audzināšanas ietvars skolām” izskaidro, kas ir rakstura audzināšana un kāpēc tā ir svarīga. Ietvars aicina visas skolas skaidri norādīt, kā tās sekmē skolēnu rakstura attīstību.
Tas ietver ‘Rakstura sastāvdaļas’: ...
Piederēt un atšķirties: romu, krievu un latviešu dzīvesstāsti Latvijā
(LU Filozofijas un socioloģijas institūts; Latvijas Mutvārdu vēstures pētnieku asociācija “Dzīvesstāsts”, 2017)
Latvijas Universitātes Filozofijas un socioloģijas institūta dzīvesstāstu pētnieku grupas kolektīvā monogrāfija “Piederēt un atšķirties: romu, krievu un latviešu dzīvesstāsti Latvijā” noslēdz Latvijas Zinātnes padomes ...
Novel octahedral tilt system a + b + c + in (1 − x)Na0.5Bi0.5TiO3–xCdTiO3 solid solutions
(Springer Verlag, 2017)
(1 − x)Na0.5Bi0.5TiO3–xCdTiO3 solid solutions in the whole concentration range (0.0 ≤ x ≤ 1.0) were studied by means of X-ray diffraction, dielectric spectroscopy and polarization measurements. The study was mainly focused ...
Direct and indirect determination of electrocaloric effect in Na0.5Bi0.5TiO3
(AIP Publishing, 2017)
Direct and indirect studies of the electrocaloric effect were carried out in poled and depoled Na0.5Bi0.5TiO3. For this purpose, polarization and electrocaloric effect temperature change measurements were made at different ...
Structural, magnetic, dielectric and mechanical properties of (Ba,Sr) MnO3 ceramics
(Elsevier Ltd, 2017)
Ceramic samples, produced by conventional sintering method in ambient air, 6H-SrMnO3 (6H-SMO), 15R-BaMnO3 (15R-BMO), 4H-Ba0.5Sr0.5MnO3 (4H-BSMO) were studied. In the XRD measurements for SMO the new anomalies of the lattice ...
All-organic electro-optic waveguide modulator comprising SU-8 and nonlinear optical polymer
(OSA - The Optical Society, 2017)
In this paper we describe the principles of operation as well as the fabrication and testing steps of an all-organic waveguide modulator. The modulator comprises an SU-8 core and an electro-optic host-guest polymer cladding. ...
Simulation of Young's moduli for hexagonal ZnO [0 0 0 1]-oriented nanowires: first principles and molecular mechanical calculations
(IOP Publishing, 2017)
Morphologically reproducible wurtzite-structured zinc oxide nanowires (ZnO NWs) can be synthesized by different methods. Since ZnO NWs have been found to possess piezoelectricity, a comprehensive study of their mechanical ...
Thin film organic thermoelectric generator based on tetrathiotetracene
(Wiley-VCH Verlag, 2017)
Thin films of p- and n- type organic semiconductors for thermo-electrical (TE) applications are produced by doping of tetrathiotetracene (TTT). To obtain p-type material TTT is doped with iodine during vacuum deposition ...
Orientation of the electric field gradient and ellipticity of the magnetic cycloid in multiferroic BiFeO3
(Taylor and Francis Ltd., 2017)
The paper deals with the hyperfine interactions observed on the 57Fe nucleus in multiferroic BiFeO3 by means of the 14.41-keV resonant transition in 57Fe and for transmission geometry applied to the random powder sample. ...
