Why do We Need High Purity Semi-insulating SiC Wafer? When SiC wafer is used as the substrate of RF devices, it is required that SiC should be semi insulating and its resistivity should be greater than 10 ^ 6 Ω· cm. In fact, the resistivity [...]
Electrical and structural properties of GaN films and GaN/InGaN light-emitting diodes grown on porous GaN templates fabricated by combined electrochemical and photoelectrochemical etching Highlights •Porous GaN template was prepared by electrochemical and photoelectrochemical etching scheme. •InGaN/GaN light-emitting diode (LED) structure was overgrown on the etched GaN template. •Overgrown [...]

Effects of post-growth annealing on the performance of CdZnTe:In radiation detectors with different thickness An effective post-growth annealing method was used to improve the performance of CdZnTe:In (CZT:In) radiation detectors. The results indicated that Te inclusions in CZT:In crystals with different thickness were eliminated completely [...]
We investigated the effects of the substrate off-angle on the m-plane GaN Schottky diodes. GaN epitaxial layers were grown by metal–organic chemical vapor deposition on m-plane GaN substrates having an off-angle of 0.1, 1.1, 1.7, or 5.1° toward . The surface of the GaN epitaxial layers on [...]
The epitaxy optimization studies of high-quality n-type AlInN alloys with different indium contents grown on two types of substrates by metalorganic vapor phase epitaxy (MOVPE) were carried out. The effect of growth pressure and V/III molar ratio on growth rate, indium content, and surface [...]
