PAM XIAMEN offers Graphene film on Ni/SiO2/Si.
Graphene is an allotrope of carbon, whose structure is one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. The term graphene was coined as a combination of graphite and the [...]

Korea’s LED Industry Developments
Korea’s LED industry took off at a much later date than Japan or Taiwan, in fact it developed at around the same time as China, but has advanced at an accelerated rate. However, the country’s LED industry plummeted much sharply compared to Japan, [...]

A novel method for estimating threshold voltage shifts of n-channel SiC MOSFETs under negative gate bias stresses has been proposed. In the proposed method, n-type SiC MOS capacitors were utilized instead of n-channel SiC MOSFETs. The n-type SiC MOS capacitors were exposed to ultraviolet [...]
