We quantified the size and concentration of Te inclusions along the lateral- and the growth-directions of a ∼6 mm-thick wafer cut axially along the center of a CdZnTe ingot. We fabricated devices, selecting samples from the center slice outward in both directions, and then [...]
PAM XIAMEN Offers Epitaxial growth of AlGaN/GaN based HEMT on Si wafers for 650V power switching device fabrication.
Recently, PAM XIAMEN, a leading supplier of GaN epitaxial wafers, announced that it has successfully developed “6-inch silicon-on-silicon (GaN-on-Si) epitaxial wafers” and its 6 inch size is on [...]

High-quality GaN films are deposited on freestanding thick diamond films by electron cyclotron resonance plasma enhanced metal organic chemical vapor deposition (ECR-PEMOCVD). The TMGa flux dependent structural, morphological, and electrical characteristics of GaN films were investigated by x-ray diffraction analysis (XRD), reflection high-energy electron [...]
The paper describes experimental results on low temperature plasma-assisted molecular beam epitaxy of GaN/AlN heterostructures on both 6H-SiC and Si(111) substrates. We demonstrate that application of migration enhanced epitaxy and metal-modulated epitaxy for growth of AlN nucleation and buffer layers lowers the screw and [...]

PAM XIAMEN offers YAG( undoped ,Ce-doped,Nd-doped).
YAG (undoped)
Undoped YAG is a substrate material that can be used for UV and IR optics. Sapphire has been the substrate of choice for these applications; however it is difficult to polish Sapphire to a 10-5 scratch-dig [...]
