Fast-Response Single-Nanowire Photodetector Based on ZnO/WS2 Core/Shell Heterostructures
(American Chemical Society, 2018)
The surface plays an exceptionally important role in nanoscale materials, exerting a strong influence on their properties. Consequently, even a very thin coating can greatly improve the optoelectronic properties of ...
Changes in structure and conduction type upon addition of Ir to ZnO thin films
(Elsevier B.V., 2017)
Zn-Ir-O (Zn/Ir ≈ 1/1) thin films have been reported to be a potential p-type TCO material. It is, however, unknown whether it is possible to achieve p-type conductivity at low Ir content, and how the type and the magnitude ...
Recombination luminescence of X-ray induced paramagnetic defects in BaY2F8
(Elsevier B.V.Journal of Luminescence, 2020)
Recombination luminescence (RL) and RL-detected electron paramagnetic resonance (RL-EPR) in BaY2F8 single crystal has been investigated after irradiation with X-rays at low temperature. The recombination process, which ...
Analysis of the U L3-edge X-ray absorption spectra in UO2 using molecular dynamics simulations
(Elsevier Ltd, 2017)
Uranium L3-edge X-ray absorption spectroscopy was used to study the atomic structure of uranium dioxide (UO2). The extended X-ray absorption fine structure (EXAFS) was interpreted within the ab initio multiple-scattering ...
Matching the Directions of Electric Fields from Triboelectric and Ferroelectric Charges in Nanogenerator Devices for Boosted Performance
(Elsevier Inc., 2020)
Embedding additional ferroelectric dipoles in contacting polymer layers is known to enhance the performance of triboelectricnanogenerator (TENG) devices. However, the influence of dipoles formed between the triboelectric ...
Influence of organic material and sample parameters on the surface potential in Kelvin probe measurements
(Springer New York LLC, 2019)
Scanning Kelvin probe is a method for material surface studies. It is used to determine the work function of metals. In the case of organic semiconductors, the measured surface potential is considered to be the Fermi level ...
Luminescence characteristics of magnesium aluminate spinel crystals of different stoichiometry
(Institute of Physics Publishing, 2019)
Magnesium aluminate spinel single crystals with different stoichiometry, MgAl2O4 (1:1 spinel) and MgO 2.5Al2O3 (1:2.5) were investigated using different optical methods (cathode-, photo- and thermally stimulated luminescence ...
Investigation of photoluminescence and amplified spontaneous emission properties of cyanoacetic acid derivative (KTB) in PVK amorphous thin films
(SPIE, 2018)
In this work photoluminescence and amplified spontaneous emission properties of new original 2-cyanoacetic acid derivative in different concentration mixed in polyvinyl carbazole (PVK) matrix were investigated. Ethyl ...
Mass recovery of carbonated fabrics of glass fibres after isothermal heating
(Institute of Physics Publishing, 2019)
Leaching of Na+ ions in sodium oxide (Na2O) and silica (SiO2) containing glass is well investigated mainly due to its weak weathering. The object of this study was naturally (at room conditions) leached, steady state product ...
Tuning the Photoresponse of Nano-Heterojunction: Pressure-Induced Inverse Photoconductance in Functionalized WO3 Nanocuboids
(John Wiley and Sons Inc., 2019)
Inverse photoconductivity (IPC) is a unique photoresponse behavior that exists in few photoconductors in which electrical conductivity decreases with irradiation, and has great potential applications in the development of ...
