High-mobility ZnVxOy/ZnO conduction path in ZnO/V/ZnO multilayer structure
Journal of Applied Physics, 2021In this study, a 300 °C-annealed 3 × 4 V/ZnO multilayer structure demonstrates the lowest resistivity (3.82 × 10−3 Ω cm) and the highest mobility (18 cm2/V s) among the studied V/ZnO multilayer structures. By measuring the energy bandgap (Eg), work function (Φ), and electron affinity (χ) by ultraviolet photoelectron spectroscopy and photoluminescence ...

ZnO nanowire field-effect transistors (FETs) were fabricated and studied in vacuum and a variety of ambient gases from 5 to 300 K. In air, these n-type nanowire transistors have among the highest mobilities yet reported for ZnO FETs (mu(e) = 13 +/- 5 cm(2) V(-1) s(-1)), with carrier concentrations averaging 5.2 +/- 2.5 x 10(17) cm(-3) and on-off ...

The pathway towards the realization of optical solid-state lasers was gradual and slow. After Einstein's paper on absorption and stimulated emission of light in 1917 it took until 1960 for the first solid state laser device to see the light. Not much later, the first semiconductor laser was demonstrated and lasing in the near UV spectral range from ZnO

Ab initio electronic structure calculations are performed to support and to help interpret the experimental work reported in the preceding manuscript. The coupled cluster singles and doubles [CCSD(T)] approach, in conjunction with a large basis set, is used to compute spectroscopic constants for the X 1Σ+ and Π3 states of ZnO and the X 2Σ+ state of ZnO−

The wet-chemical method was used to prepare the various ZnO–CNT, ZnO–CB, ZnO–GO nanocomposites, and ZnO nanoparticles in higher pH medium, which were finally utilized with 5% nafion to produce a thin film of NCs/Nafion/GCE sensor that has a faster response towards selected xanthine with higher sensitivity, lower detection limit, and large linear ...

Solar paint of ZnO/CdS and ZnO/CdSe based on commercial ZnO
Functional Materials Letters, 2016We report a facile and cheap route to the fabrication of ZnO/CdS and ZnO/CdSe based on commercial ZnO particles. The obtained product can be directly brush printed as solar paint. The results show that the solar cell based on the mixture of ZnO/CdS and ZnO/CdSe have a better light absorption and electron transport ability, and a high power conversion ...

Adsorption of ZnO, (ZnO)2 and (ZnO)3 on MgO(001)
Surface Science, 2008Abstract We have investigated the adsorption of ZnO, atomic Zn, atomic O and (ZnO) n on the flat MgO(0 0 1) surface by means of density functional calculations. A single ZnO molecule prefers to bind in a position parallel to the surface with the zinc atom above a surface oxygen atom and the oxygen above a magnesium atom.
