Tribovoltaic effect is an emerging phenomenon occurring between two materials, which can generate direct current (DC) rather than alternate (AC) at the contact interface. Though existence of a tribovoltaic indeed brings up new method for power supply critical sensors using Internet Things technology, wear and damage materials related to surface topography during sliding process still nonnegligible. In this work, influence on semiconductors investigated by means lateral mode triboelectric...
In this paper, a high-temperature heat pump (HTHP) is developed and manufactured to replace the traditional oil-fired boiler heater for crude oil heating. It extracts thermal energy from waste hot water separated provide oil. A prototype of HTHP system installed in Jinzhou treatment station Liaoning, China field test conducted about 6000 h. typical 144 h testing data analyzed evaluate performance designed system. observed that temperature provided by unit varies 86 ℃ 95 throughout whole...
Suppression of secondary electron yield attracted much attention in areas such as accelerator and high power microwave components recent years. To evaluate the suppression efficiencies different surface topographies, yields (SEYs) four kinds micro-structured surfaces for trapping electrons, i.e., triangular groove, rectangular cuboid, cylindrical, are obtained by phenomenological probabilistic model emission. The simulation results show that SEYs these structures dependent on shape...
The piezo-phototronic effect uses the piezoelectric potential/piezoelectric charge generated by semiconductor material to regulate energy band structure and photogenerated carrier behavior at interface/junction, thereby modulating device's performance. positive/negative charges interface of semiconductors can reduce electron/hole barriers thus enhance transport carriers. However, potential wells are formed when barrier caused is lowered too much, hindering It difficult balance relationship...
Ag-ZnO-Ag X-ray detectors based on ZnO film and nanowires are both fabricated in this paper. Results of continuous radiation measurement show that the two have high responsivity: responsivity device is about 0.12 μC/Gy under a 100 V bias voltage, 0.15 50 voltage. Surface effect due to absorption desorption oxygen surface, which makes carrier lifetime increase, decisive responsivity. their potential applications dose rate measurement.
The controllable growth processes of ZnO nanowires by evaporation metal zinc with high purity and its luminescence properties have been investigated in detail. Firstly, the power yield homogeneous dimension was synthesized using special quartz boat at 600 °C. Then, oriented about 20 nm diameter were a 90 nm-thick layer nanocrystals on Si substrate as seed layer. Both fabrication are repeatable no catalysts necessary. Finally, photoluminescence (PL) spectroscopy for an He–Cd laser line 325...
Sugarcane is one of the most important economic crops in Guangxi.
