Anticipating exploding demand for blue LED chips, Xiamen Powerway Advanced Material Co.,Ltd. (PAM-XIAMEN) shift a GaN LED production line from the current 2-inch-wafer-based operation to 4-inch-wafer facilities within a couple of years.
“We have established the production process based [...]
What is the Growth Facet?
In the central region of SiC {0001} wafer, the doping concentration is usually relatively high, such as the dark color observed in the central region, which is due to the enhanced impurity doping in facet growth, as shown in Fig. [...]

Sublimation epitaxy under vacuum (SEV) was investigated as a method for growing 4H-SiC epitaxial structures for p–i–n diode fabrication. The SEV-grown 4H-SiC material was investigated with scanning electron microscopy (SEM), atomic force microscopy (AFM), x-ray diffraction, photo-luminescence spectroscopy (PL), cathodo-luminescence (CL) spectroscopy, photocurrent method [...]
