Free-Standing & Bulk GaN Substrates for Laser Diode, LED and Power Electronics
LED applications will become the driving force of the bulk GaN market, surpassing established laser diode (LD) and emerging power electronics segments. However, major changes could occur if 4″ bulk GaN price gets [...]

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 [...]
