Pair vacancy defects in β-Ga2O3 crystal: Ab initio study
(Elsevier, 2022)Despit many studies dedicated to the defects in β-Ga2O3, information about formation processes of complex “donor-acceptor” defects in β-Ga2O3 and their energetic characteristics is still very scarce. Meanwhile, complex ... -

Par oskulāciju, superoskulāciju un charakteristiskiem punktiem
(1943-04)No Dr. A.Lūša raksturojuma E.Grinberga zinātniskajam darbam: Doktora disertacija, ko E.Grīnbergs sācis strādāt 1940/41 m.g. Latvija Valsts Universitātē un aizstāvējis Rīgas Universitātē 1944.g. /oponenti prof.Dr.A.Lūsis, ... -
Par viduslejasvācu valodas pēdām latviešu īpašvārdos
(Vilniaus universitetas, 2020)The great impact of Middle Low German on the Latvian language during the 13–16th century is a well-known and rather widely researched fact. However, the main focus of linguists' attention has so far been on the apellative ... -
Paramagnetic Defects and Thermoluminescence in Irradiated Nanostructured Monoclinic Zirconium Dioxide
(MDPI, 2022)The ESR spectra of nanostructured samples of monoclinic ZrO2 irradiated by electrons with energies of 130 keV, 10 MeV, and by a beam of Xe ions (220 MeV) have been studied. It has been established that irradiation of samples ... -

Particle size effects on the structure and emission of Eu3+:LaPO4 and EuPO4 phosphors
(Elsevier B.V., 2018)This paper provides the detailed study of (nano)particle's size effect on structural and luminescent properties of LaPO4:Eu3+ synthesized by four different methods: high temperature solid-state, co-precipitation, reverse ... -
Patiesības izpratne Latvijas filosofijā 20. gadsimta divdesmitajos un trīsdesmitajos gados: Teodors Celms un Jūlijs Aleksandrs Students
(LU Filozofijas un socioloģijas institūts, 2011)Rakstā aplūkoti Latvijas pirmās neatkarības laika filozofu Teodora Celma un Jūlija Aleksandra Studenta uzskati par jēdzienu "patiesība", šī jēdziena skaidrojumi un patiesības teorijas. -

Peculiarities of Phase Formation in Mn-Based Na SuperIonic Conductor (NaSICon) Systems: The Case of Na1+2 xMnxTi2- x(PO4)3(0.0 ≤ x ≤ 1.5)
(American Chemical Society, 2021)NAtrium SuperIonic CONductor (NASICON) structured phosphate framework compounds are attracting a great deal of interest as suitable electrode materials for "rocking chair"type batteries. Manganese-based electrode materials ... -
Peculiarities of the diffusion-controlled radiation defect accumulation kinetics under high fluencies
(Elsevier B.V., 2020)Theory is developed for kinetics of the diffusion-controlled radiation defect accumulation in crystalline solids under high fluencies taking into account recently observed correlation between the defect diffusion energy ... -
Peculiarities of the local structure in new medium- and high-entropy, low-symmetry tungstates
(Elsevier, 2022)New monoclinic (/) tungstates – a medium-entropy tungstate, (MnNiCuZn)WO4, and a high-entropy tungstate, (MnCoNiCuZn)WO4 – were synthesized and characterized. Their phase purity and solid solution nature were confirmed by ... -
Performance and characterization of the FinEstBeAMS beamline at the MAX IV Laboratory
(Wiley-Blackwell, 2021)FinEstBeAMS (Finnish-Estonian Beamline for Atmospheric and Materials Sciences) is a multidisciplinary beamline constructed at the 1.5 GeV storage ring of the MAX IV synchrotron facility in Lund, Sweden. The beamline covers ... -
Permanent photodoping of plasmonic gallium-ZnO nanocrystals
(Royal Society of Chemistry, 2020)Donor dopants in oxide semiconductors are compensated not only by valuable electrons but also by other point defects, leading to a decrease in electric conductivity and infrared absorption. We demonstrate that the electron ... -
Perovskite CH3NH3PbI3–XClx Solar Cells and their Degradation (Part 1: A Short Review)
(De Gruyter, 2021)Development of hybrid organic-inorganic perovskite solar cells (PSC) has been one of the hottest research topics since 2013. Within brief literature review, we would like to achieve two objectives. Firstly, we ... -
Perovskite CH3NH3PbI3–XClx Solar Cells. Experimental Study of Initial Degradation Kinetics and Fill Factor Spectral Dependence
(De Gruyter, 2021)The main drawback of the methylammonium lead halide perovskite solar cells is their degradation in ambient atmosphere. To investigate ambient-air-induced cell degradation, spec-tral dependencies of open-circuit ... -
