X-ray absorption spectroscopy and Eu3+-emission characteristics in GaAs/SnO2 heterostructure
(Springer, 2020-08-28)
X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) data are used for investigating heterostructure samples of GaAs/SnO2. XANES data are used for analyzing the local organization ...
Photoluminescence of Rare-Earth Ions in the Nanocrystalline GaAs/SnO2 Heterostructure and the Photoinduced Electrical Properties Related to the Interface
(Mdpi Ag, 2017-03-01)
Deposition of an SnO2 thin film was carried out by sol-gel-dip-coating and doped with Ce3+ or Eu3+, and a GaAs layer was deposited by resistive evaporation or sputtering. This investigation combines the emission properties ...
Thermal Annealing Influence on the Properties of Heterostructure Based on 2 at.%Eu Doped SnO2 and Cu1.8S
(2018-12-01)
Aiming at optoelectronic applications, a heterostructure based on Eu-doped tin oxide (SnO2) and copper sulfide (Cu2−xS) is built. SnO2 thin films doped with 2 at.% Eu were obtained by the sol–gel dip-coating and spin-coating ...
Magnetoelectric coupling of LaFeO3/BiFeO3 heterostructures
(2015-03-12)
BiFeO3 (BFO) and LaFeO3 (LFO) heterostructures were obtained at room temperature on Pt/TiO2/SiO2/Si (100) substrates by chemical solution deposition. The films were coherently grown at a temperature of 500°C for 2h. The ...
Light localization in one-dimensional photonic crystal heterostructures
(2021-12-01)
Effects of both metamaterial inclusion and lack of inversion symmetry on the localized modes in one-dimensional photonic heterostructures under normal incidence are investigated. Each structure consists of two semi-infinite ...
Structural, electronic and magnetic properties of YMnO3/La0.7Sr0.3MnO3 heterostructures
(International Union of Crystallography, 2014-06)
Heterostructures with competing magnetic interactions are often exploited for their tailored new functionalities. Exchange bias is one such outcome of interfacial coupling across ferromagnetic-antiferromagnetic, ...
Direct photo-oxidation and superoxide radical as major responsible for dye photodegradation mechanism promoted by TiO2–rGO heterostructure
(2018-10-01)
The increase in photocatalytic activity of reduced graphene oxide–TiO2 heterostructures under ultraviolet and visible illumination is already well known, as the photocatalyst mechanism modifications with heterostructure ...
Photo-induced electrical behavior under gas adsorption on SnO2 -based heterostructures
(2020-11-15)
Er-doped SnO2 thin films are produced by a combined technique where films are deposited by resistive evaporation from a precursor powder obtained by sol-gel. Films are deposited on different substrates and analyzed concerning ...
Structural and optical properties of ZnS/MgNb2O6 heterostructures
(Elsevier B.V., 2015-03-01)
In this letter, we report a simple and efficient synthetic procedure where the first step is a coprecipitation/calcination method used to obtain magnesium niobate MgNb2O6 (MN) nanoctystals and in the second stage a microwave ...
