We report the synthesis of oriented single crystalline Mn doped ZnO nanowires through a hydrothermal method. Structural characterizations using X-ray diffraction and transmission electron microscopy revealed that the Mn was doped into the lattice structure, forming solid solution. The Mn doped ZnO nanowires possess wurtzite structure with a c-axis growth orientation. The physical properties of ...

We investigated the influence of low-concentration indium (In) doping on the chemical and structural properties of solution-processed zinc oxide (ZnO) films and the electrical characteristics of bottom-gate/top-contact In-doped ZnO thin-film transistors (TFTs). The thermogravimetry and differential scanning calorimetry analysis results showed that thermal annealing at 400 °C for 40 min produces...

Abstract We report here the structural, optical, photoluminescence (PL), and magnetic investigation of Zn 1−x−y Fe x M y O nanoparticles. The lattice constants crystallite size are decreased by Fe, followed a further decrease up to (Fe + M) = 0.30. A compressive stress is approved particle between 180 277 nm follows sample order ZnO, Cu), Ni), Fe. Although single value energy gap (E g ) found f...

Three methods were used to fabricate ZnO-based room temperature liquid petroleum gas (LPG) sensors having interdigitated metal-semiconductor-metal (MSM) structures. Specifically, devices with Pd Schottky contacts were fabricated with: (1) un-doped ZnO active layers; (2) Pd-doped ZnO active layers; and (3) un-doped ZnO layers on top of Pd microstructure arrays. All ZnO films were grown on p-type...

We report, for the first time, the synthesis of the high-quality p-type ZnO NWs using a simple chemical vapor deposition method, where phosphorus pentoxide has been used as the dopant source. Single-crystal phosphorus doped ZnO NWs have their growth axis along the 001 direction and form perfect vertical arrays on a-sapphire. P-type doping was confirmed by photoluminescence measurements at vario...

Cu-doped p-type ZnO films are grown on c-sapphire substrates by plasma-assisted molecular beam epitaxy. Photoluminescence (PL) experiments reveal a shallow acceptor state at 0.15 eV above the valence band edge. Hall effect results indicate that a growth condition window is found for the formation of p-type ZnO thin films, and the best conductivity is achieved with a high hole concentration of 1...

PURPOSE To evaluate changes in the physicochemical properties, water sorption (WS), solubility (SO), modulus of elasticity (E), ultimate tensile strength (UTS), and microhardness (MH) tests were undertaken in zinc-doped dental adhesives. METHODS Two bonding resins, Adper Single Bond Plus (SB) and Clearfil SE Bond (SEB), were zinc-doped by mixing them with 5, 10 or 20 wt% of ZnO powder, or wit...

The aqueous-based Zn-ammine complex solutions represent one of the most promising routes to obtain the ZnO electron transport layer (ETL) at a low temperature in inverted organic solar cells (OSCs). However, to dope the ZnO film processed from the Zn-ammine complex solutions is difficult since the introduction of metal ions into the Zn-ammine complex is a nontrivial process as ammonium hydroxid...

Abstract Fe-doped ZnO nanoparticles (NPs) with different Fe contents (0.1–5.0 wt%) were prepared using extract of wild olive leaves growing in Saudi Arabia (region Abha). The biosynthesized NPs characterized by Fourier transform infrared spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller, scanning electron microscopy, transmission and photoluminescence (PL). Characterization results showed...
