CONDUCTOMETRIC GAS SENSORS BASED ON METAL OXIDES MODIFIED WITH GOLD NANOPARTICLES: A REVIEW

Korotcenkov, Ghenadii; Brinzari, Vladimir; Cho, Beong K. (Springer, 2016)

This review (with 170 refs.) discusses approaches towards surface functionalizaton of metal oxides by gold nanoparticles, and the application of the resulting nanomaterials in resistive gas sensors. The articles is subdivided ...
ELECTRONIC STRUCTURE AND STRUCTURAL DEFECTS IN 3d-METAL DOPED In2O3

Ho, J.; Becker, J.; Leedahl, B.; Boukhvalov, D. W.; Zhidkov, I. S.; Kukharenko, A. I.; Kurmaev, E. Z.; Cholakh, S. O.; Gavrilov, N. V.; Brinzari, Vladimir; Moewes, A. (Springer, 2019)

Dilute magnetic semiconductors (DMSs) are a highly attractive field of research due to their potential to open new technological functionality. Here, we perform a systematic study of In2O3 thin films with dopant ions of ...
ENERGETIC, STRUCTURAL AND ELECTRONIC FEATURES OF Sn-, Ga-, O-BASED DEFECT COMPLEXES IN CUBIC In2O3

Cocemasov, Alexandr; Brinzari, Vladimir; Nika, Denis (IOP Publishing Ltd, 2020)

Defect energy formation, lattice distortions and electronic structure of cubic In2O3 with Sn, Ga and O impurities were theoretically investigated using density functional theory. Different types of point defects, ...
FUNDAMENTAL CRYSTAL FIELD EXCITATIONS IN MAGNETIC SEMICONDUCTOR SnO2: Mn, Fe, Co, Ni

Brinzari, Vladimir; Leedahl, B.; McCloskey, D. J.; Boukhvalov, D. W. (Royal Society of Chemistry, 2019)

Directly measuring elementary electronic excitations in dopant 3d metals is essential to understanding how they function as part of their host material. Through calculated crystal field splittings of the 3d electron band ...
In2O3- AND SnO2-BASED OZONE SENSORS: DESIGN AND CHARACTERIZATION

Korotcenkov, Ghenadii; Brinzari, Vladimir; Cho, B.K. (Taylor & Francis Ltd, 2018)

This article describes in detail the SnO2 and In2O3 metal oxides as materials for designing solid state conductometric ozone sensors. The main focus of this article is on the description of the SnO2 and In2O3 films' ...
In2O3-BASED THERMOELECTRIC MATERIALS: THE STATE OF THE ART AND THE ROLE OF SURFACE STATE IN THE IMPROVEMENT OF THE EFFICIENCY OF THERMOELECTRIC CONVERSION

Korotcenkov, Ghenadii; Brinzari, Vladimir; Ham, Moon-Ho (MDPI, 2018)

In this paper, the thermoelectric properties of In2 O3 -based materials in comparison with other thermoelectric materials are considered. It is shown that nanostructured In2 O3 Sn-based oxides are promising for thermoelectric ...
THE INFLUENCE OF GOLD NANOPARTICLES ON THE CONDUCTIVITY RESPONSE OF SnO2-BASED THIN FILM GAS SENSORS

Korotcenkov, Ghenadii; Brinzari, Vladimir; Gulina, L.B.; Cho, B. K. (Elsevier, 2015)

The results presented in this study demonstrate that the successive ionic layer deposition (SILD) method for gold nanoparticle formation can be used for surface functionalization of SnO2 films to improve their gas sensing ...
KINETIC APPROACH TO RECEPTOR FUNCTION IN CHEMIRESISTIVE GAS SENSOR MODELING OF TIN DIOXIDE. STEADY STATE CONSIDERATION

Brinzari, Vladimir; Korotcenkov, Ghenadii (Elsevier, 2018)

Kinetic approach in phenomenological modeling of SnO2 chemiresistive gas sensor is proposed. It is based on a new perception of chemisorbed oxygen forms and consistent account of main reaction rates into a balance equation ...
THERMAL TRANSPORT EVOLUTION DUE TO NANOSTRUCTURAL TRANSFORMATIONS IN Ga-DOPED INDIUM-TIN-OXIDE THIN FILMS

Brinzari, Vladimir; Jeong, Do-Gyeom; Korotcenkov, Ghenadii; Vatavu, Sergiu; Lee, Jong S.; Nika, Denis; Cocemasov, Alexandr (MDPI, 2021)

We report on a comprehensive theoretical and experimental investigation of thermal conductivity in indium-tin-oxide (ITO) thin films with various Ga concentrations (0–30 at. %) deposited by spray pyrolysis technique. X-ray ...
XPS STUDY OF Rh/In2O3 SYSTEM

Korotcenkov, Ghenadii; Brinzari, Vladimir; Nehasil, Vaclav (Elsevier, 2021)

The effect of surface modification of In2O3 films by rhodium atoms deposited by electron beam sputtering on the XP spectra is considered. The surface coverage with rhodium ranged from 0 to 0.1 ML. It was shown that the ...
XPS STUDY OF THE SnO2 FILMS MODIFIED WITH Rh

Korotcenkov, Ghenadii; Brinzari, Vladimir; Hanyš, P.; Nehasil, V. (John Wiley and Sons, 2018)

In this paper, we have analyzed the effect of the rhodium surface modification on the surface state of SnO2 films. SnO2 films, subjected for the surface modification, were deposited by spray pyrolysis, while Rh was deposited ...
