A fracture criterion for gallium arsenide wafers
The fracture of single crystal gallium arsenide (GaAs) semi-conducting wafers was studied. Prismatic beam specimens, cut at different crystallographic orientations from thin wafers, were loaded to failure in four-point bending. Fracture in these crystals occurred predominantly on the [...]
Bulk GaN cost to fall 60% to $730 for 2″ substrate by 2020
Wide-bandgap semiconductor materials such as gallium nitride (GaN) offer far higher performance than traditional silicon but cost significantly more. However, by 2020 GaN costs will drop enough for it to become competitive [...]

Cubic SiC films (3C–SiC) were deposited on (111) Si substrates by a vapor–liquid–solid tri-phase growth method. In such a process a thin copper layer, which was evaporated on the Si substrate prior to the growth, was melted at high temperature as the flux and [...]

Actually, gallium oxide(Ga2O3) is not a new technology. Studies on gallium oxide applications in the field of power semiconductors are carried out by companies and research institutions all the time. And the gallium oxide material is mainly from Japan. With the development of Ga2O3 applications requirements becoming clearer, the performance requirements for high-power devices are getting [...]

You can buy single crystal AlN substrate with higher photoelectric conversion efficiency than indirect band gap semiconductors from PAM-XIAMEN. Aluminum nitride (AlN) is an important blue and ultraviolet light-emitting material, which is used in ultraviolet/deep ultraviolet light-emitting diodes, ultraviolet laser diodes, and ultraviolet detectors.
