Influence of Nb-doping on the local structure and thermoelectric properties of transparent TiO2:Nb thin films
Ribeiro, , J. M.; Correia, Filipe C.; Kuzmin, Alexei; Jonane, Inga; Kong, M.; Goñi, Alejandro R.; Reparaz, Sebastian; Kalinko, Aleksandr; Welter, Edmund; Tavares, C. J.M. (Elsevier Ltd, 2020)Transparent n-type niobium-doped titanium dioxide thin films (TiO2:1.5 at.%Nb) with pronounced thermoelectric properties were produced from a composite Ti:Nb target by reactive magnetron sputtering. The thin films were ... -
The influence of Sb doping on the local structure and disorder in thermoelectric ZnO:Sb thin films
Ribeiro, Joana M.; Rodrigues, Frederico J.; Correia, Filipe C.; Pudza, Inga; Kuzmin, Alexei; Kalinko, Aleksandr; Welter, Edmund; Barradas, Nuno P.; Alves, Eduardo; LaGrow, Alec P.; Bondarchuk, Oleksandr; Welle, Alexander; Telfah, Ahmad; Tavares, Carlos J. (Elsevier, 2023)Thermoelectric transparent ZnO:Sb thin films were deposited by magnetron sputtering, with Sb content varying between 2 and 14 at%. As evidenced by X-ray diffraction analysis, the films crystallize in the ZnO wurtzite ... -
The influence of Zn2+ ions on the local structure and thermochromic properties of Cu1-xZnxMoO4 solid solutions
Pudza, Inga; Anspoks, Andris; Cintins, Arturs; Kalinko, Aleksandr; Welter, Edmund; Kuzmin, Alexei (Elsevier, 2021)The influence of zinc ions on the thermochromic properties of polycrystalline CuZnMoO (=0.10, 0.50, 0.90) solid solutions was studied by X-ray absorption spectroscopy at the Cu, Zn and Mo K-edges. Detailed structural ... -
Peculiarities of the local structure in new medium- and high-entropy, low-symmetry tungstates
Bakradze, Georgijs; Welter, Edmund; Kuzmin, Alexei (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 ... -
The role of Ga and Bi doping on the local structure of transparent zinc oxide thin films
Correia, Filipe C.; Ribeiro, Joana M.; Kuzmin, Alexei; Pudza, Inga; Kalinko, Aleksandr; Welter, Edmund; Mendes, Adelio; Rodrigues, Joana; Ben Sedrine, Nabiha; Monteiro, Teresa; Correia, Maria Rosário; Tavares, Carlos J. (Elsevier, 2021-07-25)Transparent undoped ZnO and additionally doped with Ga and Bi thin films were produced by magnetron sputtering. The thin films were comprehensively characterized by X-ray absorption, X-ray diffraction (XRD), X-ray photoelectron ... -
Unraveling the interlayer and intralayer coupling in two-dimensional layered MoS2 by X-ray absorption spectroscopy and ab initio molecular dynamics simulations
Pudza, Inga; Bocharov, Dmitry; Anspoks, Andris; Krack, Matthias; Kalinko, Aleksandr; Welter, Edmund; Kuzmin, Alexei (Elsevier, 2023)Understanding interlayer and intralayer coupling in two-dimensional layered materials (2DLMs) has fundamental and echnological importance for their large-scale production, engineering heterostructures, and development of ...
