The effects of GaN channel layer thickness on dc and RF performance AlGaN/GaN high-electron mobility transistors (HEMTs) with a state-of-the-art composite (1/1 μm) buffer were systematically investigated. Although HEMTs thick exhibit slight degraded small-signal associated short-channel effects, they demonstrate significantly enhanced OFF-state breakdown voltage large-signal performance. 1-mm 150-nm-thick feature 1.4 dB higher saturated POUT about 10% PAE than that 50-nm-thick layer, in both...
Low-pressure chemical vapor deposition (LPCVD) technique is utilized for SiN <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> passivation of AlGaN/GaN high-electron-mobility transistors (HEMTs). A robust / AlGaN interface featuring high thermal stability and well-ordered crystalline structure achieved by a processing strategy “passivation-prior-to-ohmic” in HEMTs fabrication. Effective suppression surface-trap-induced current collapse...
Single-nozzle based multimaterial direct ink writing enables voxel-based fabrication with superior printing efficiency than multi-nozzle protocol. This is attractive for food 3D process where matters its application. However, single-nozzle process, the presence of residual material in shared channel can affect fidelity. In this study, we propose a path planning algorithm that address issue by incorporating (i) advance distance to compensate extrusion delay when switching materials, and (ii)...
Since that setting frequency signal as an agent can provide the distributed generations (DGs) with opportunities to adaptively maintain supply and demand balance, a new energy management strategy modified droop control for islanded microgrid containing photovoltaic (PV)/battery/fuel cell (FC)-eletrolyser is proposed in this study. Without communication line or central supervisor, three power sources operate mode PV units track offer maximum order make full use of energy, battery regulate...
A heat pump is applied in pressure-swing distillation (PSD) for separating an isobutanol/isobutyl acetate mixture this paper. To ensure dry compression and prevent compressor damage, a preheater added before the based on fluid property of mixture. In addition, optimal preheated temperature overhead vapor stream may further improve performance pump-assisted PSD process. Through optimization analysis, optimum superheat values streams from two columns are 12 8.4 °C, respectively. The...
This study evaluated Al-ZSM-5 nanocrystals grown from silicalite-1 seed crystals as catalysts for the methane dehydroaromatization (MDA) reaction. Silicalite-1 sized between 30 and 40 nm were used to grow under various synthesis conditions. The size of was significantly affected by Si/Al ratio (SAR), time, silica nutrients/seed crystal (NSR). Larger obtained with an increased SAR in sols. Gradual growth occurred although ceased at 5 h 120 °C, indicating rapid aided seeds. Precise tuning...
Low cost stainless steels (SS) with high performance, especially good mechanical properties and oxidation resistance at temperature, are continuous pursuit for manufacture industry. To achieve combination of properties, cost, nanoprecipitate strengthened alumina forming austenitic (NSAFA) SS have been developed by removing expensive elements such as Nb Ta, lowering Ni concentration in Fe-26Ni-15Cr-1.5Mo-(2.8-3.5)Al-(1-2.35)Ti (wt.%) alloys. Microstructure investigation demonstrates that...
Red-green-blue white light-emitting diodes (RGB-WLEDs) have great potential as commercial solid-state lighting devices, well visible light communication because of their high color-rendering index (CRI) and response frequency. The quality an RGB-WLED strongly depends on its spectral parameters. In this study, we fabricated RGB-WLEDs with red, blue, green LEDs measured the power distribution (SPD). experimental SPD is consistent calculated spectrum. We also SPDs different peak wavelengths...
Polyvinyl alcohol (PVA)/CNT composite membranes were prepared without adding cross-linkers; herein, carboxylated CNTs served as alternative cross-linkers. A molecular simulation confirmed the cross-linking capability between and PVA chains, which led to prediction that cross-linked PVA/CNT complex would be stable in water. To realize simulated outcome, multiwalled activated functionalized via sonication methods subsequent acid treatment. The membranes, including treated by probe sonication,...
An increasing number of monitoring systems have been developed in smart cities to ensure that a city's real-time operations satisfy safety and performance requirements. However, many existing city requirements are written English with missing, inaccurate, or ambiguous information. There is high demand for assisting policy makers converting human-specified machine-understandable formal specifications systems. To tackle this limitation, we build CitySpec, the first intelligent assistant system...
A single crystalline GaN film on Si(111) with a buffer layer is grown by simple reactive evaporation method. Scanning electron microscopy, x-ray diffraction (XRD), transmission microscopy (TEM), photoluminescence measurement (PL), and Hall results indicate that the wurtzite was successfully microcrystalline layers substrate. The surface of films mirror-like crack-free. pronounced (0002) peak appears in XRD pattern. full width at half maximum (FWHM) double-crystal rocking curve for from...
Three-dimensional NAND flash memory featuring dozens of vertically stacked cells is the state-of-the-art technology for most storage platforms. To fabricate three-dimensional (3D) memory, lateral etching Si3N4 layer over SiO2 an essential step that conducted through a wet process using phosphoric acid-based etchant. Silyl-phosphate or highly selective nitride serves as solution additive to control dissolution rate. However, silyl-phosphate prepared with expensive monomeric silica precursor...
