Yole Développement is releasing, this week, the "GaN-on-Si Substrate Technology and Market for LED and Power Electronics" report. Analysts believe that GaN-on-silicon technology will be widely adopted by power electronics applications. The power electronics market addresses applications such as AC to DC or DC to AC conversion, which is always associated with substantial energy losses that increase with higher power and operating frequencies. Incumbent silicon based technology is reaching its limit and it is difficult to meet higher requirements.
