In this paper, a varactor with metal–semiconductor–metal diodes on top of the (NH 4) 2 S/P 2 S 5-treated AlGaN/GaN two-dimensional electron gas epitaxial structure (MSM-2DEG) is proposed to the surge protection for the first time. The sulfur-treated MSM-2DEG varactor properties, including current–voltage (I–V), capacitance–voltage (C–V), and frequency response of the proposed surge protection c...

Appropriate preparation routes allow designing and improving the performances of ceramic-based functional composites. In this work, two powder-preparation methods enabled by cold sintering process are utilized to fabricate unique ZnO-based varistor The thermoplastic polymer, poly-ether-ether-ketone (PEEK), has been successfully integrated with ZnO form dense ZnO-PEEK With a dissolution method, ...

Sub-micrometer-sized (0.33 μm) polycrystalline powders of calcium copper titanate (CCTO) were synthesized via the solgel method. Compacted calcined sintered at 900 °C/2h to obtain porous (<80% density) pellets. Subsequently, ZnO or SnO 2 pastes (∼10 μm grain size) smeared on either side pellets and 1100 °C/15 h, which yielded dense (>95% ceramics. X-ray structural investigations revealed ...
