Zn0.8Co0.2O and Zn0.8Mn0.2O films were deposited on substrates by a sol–gel technique. X-ray diffraction, field-emission scanning electron microscopy, photoluminescence, and ferromagnetism measurements were used to characterize these dilute magnetic semiconductors. It is shown that the ferromagnetic properties might be related to the formation of acceptor-like defects in the Zn0.8Co0.2O and Zn0.8Mn0.2O films. It is found that ferromagnetic Zn0.8Mn0.2O has a higher Curie temperature than Zn0.8Co0...

Abstract This study investigates the effect of ultraviolet treatment on the structural and optical properties of the ZnO nanoparticles by X-ray diffraction, scanning electron microscopy, Fourier-transform infrared spectroscopy and photoluminescence measurements. A dependence of the luminescence behavior and crystal structure upon ultraviolet treatment has been found. It is shown that ultraviolet treatment may lead to the formation of surface oxygen vacancies, producing hydroxyl adsorption. The s...

Abstract In this study, the current–voltage characteristics of the AlCdO/unpolished p-type Si and AlCdO/polished p-type Si Schottky diodes with and without light illumination were examined. It is found that the Schottky barrier height (the series resistance) of the AlCdO/unpolished p-type Si Schottky diode is higher (lower) than that of the AlCdO/polished p-type Si Schottky diode. The power conversion efficiency of the AlCdO/p-type Si devices in the light (AM 1.5 G, 100 mW/cm 2 ) was improved by...

The discrepancy in mobility extracted from transfer and output characteristics of organic thin film transistors was studied. The extraction from transfer characteristics demonstrates higher mobility, compared to the extraction from output characteristics. It is shown that the contribution of capacitance variation may lead to an increased drain current, thus overestimating mobility.

This study investigates the effect of Li content on the structural, optical, and electrical properties of sol-gel LiZnMgO films by x-ray diffraction, scanning electron microscopy, photoluminescence, and conductivity measurements. A dependence of crystallite size and conduction type upon Li content has been found. The abnormal shift of the (002) diffraction peak position determined from x-ray diffraction measurements and conduction type determined by Hall effect measurements are closely related t...

Capacitance-voltage and current-voltage characteristics of Au/n-type Si (n-Si) and Au/poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT:PSS)/n-Si Schottky diodes were investigated in this study. The interfacial phenomenon was explained in terms of the generation of an interfacial dipole subsequently affecting the electron-injection barrier. The authors found that inserting a PEDOT:PSS layer at the Au/n-Si interface may result in the formation of an interfacial dipole, i...

Co0.2AlxZn0.8−xO films prepared with different molar ratio of aluminum nitrate to zinc acetate were deposited on substrates by the sol–gel technique. X-ray diffraction, photoluminescence and ferromagnetism measurements were used to characterize the Co0.2AlxZn0.8−xO diluted magnetic semiconductors. The authors found that the intensity of the acceptor-related photoluminescence increased with increasing aluminum concentration and an increase in the number of the acceptor-like defects (zinc vacancie...

We report on the effect of ultraviolet (UV) treatment on the specific contact resistance (ρ) and electronic transport at the Ti/ZnO interfaces. The experimental results show the same barrier height of Ti/ZnO samples without UV treatment as Ti/ZnO samples with UV treatment and the higher ρ of Ti/ZnO samples with UV treatment than Ti/ZnO samples without UV treatment, suggesting the barrier-height independence of ρ. Based on the thermionic-emission model and x-ray photoelectron spectroscopy results...
