High-k hafnium oxide (HfO2) film was prepared by high power impulse magnetron sputtering (HiPIMS). The influences of oxygen supply on the plasma state, properties and TFT performance were investigated. films are near-stoichiometric preferentially (−1 1 1)-orientated. When increased from 1% to 3%, excitation/ionization rate species increased, leading higher crystallinity, density lower vacancy defect concentration film, therefore improving dielectric film. further 5%, decreased thereby led...
The development of silicon wafers in the photovoltaic industry towards larger and thinner sizes requires ultrafine tungsten wires, uniform coating high-performance graphite emulsion is key to ensuring quality wires. However, existing mainly depends on imports, limited domestic self-made lotion shows poor dispersion stability nonuniform surface coating. This study provides a strategy enhance rheological property by introducing carboxymethyl cellulose (CMC). with 1.0% CMC addition has best...
High-performance P-type cuprous oxide (Cu2O) film was prepared at room temperature by high power impulse magnetron sputtering. Optical emission spectra revealed that the ratio of Cu radicals/ions in plasma significantly decreased with increasing process pressure due to reduction sputtering yield as target surface oxidized increased oxygen radicals/ions. In addition, increase self-sputtering for cations reduced arrival species substrate surface. As a result, crystal phase transformed from...
It is usually difficult to realize high mobility together with a low threshold voltage and good stability for amorphous oxide thin-film transistors (TFTs). In addition, fabrication temperature preferred in terms of enhancing compatibility the back end line device. this study, α-IGZO TFTs were prepared by high-power impulse magnetron sputtering (HiPIMS) at room temperature. The channel was under two-step deposition pressure process modulate its electrical properties. X-ray photoelectron...
In this article, the tunable Zn-doped Ga2O3 films were obtained by introducing ZnO intercalation during film deposition using plasma-enhanced atomic layer (PEALD). The effect of cycle ratio on performance solar-blind photodetectors (PDs) was first analyzed. Compared to pure Ga2O3, an obviously enhanced PDs observed introduction Zn dopants, especially photocurrent or responsivity, even if light intensity is low. A high sensitivity PD has been achieved with superior photoelectric...
The high temperature in asphalt pavement during summer accelerates the rutting and aggravates phenomenon of urban heat island (UHI). One mitigation methods is use heat-reflective coating (HRC) on pavement. However, conventional HRC faces some challenges such as poor abrasion resistance, skid resistance environment pollution. In this paper, a new type coating, named thermosetting powder (TPC), was developed for reflecting off Four types TPCs, including polyester (PPC), modified (MPPC),...
The research was to develop a small blade fatigue test system which met the criterion of IEC (TR 61400-23) for composite wind turbine blades (SCWTBs). machine consisted servo motor, linear guide, transmission, controlling and clamping apparatuses. These components were used balance weights loaded on blades. Weights added change different mass at each saddle loading tests. Amplitude can be manipulated by rotating eccentric holes flywheel. kinetic power SCWTBs translated from circular motion...
