Heteroepitaxial growth and power electronics using AlGaN/GaN HEMT on Si
Developments of heteroepitaxial growth and characteristics of an AlGaN/GaN HEMT on a Si substrate are reported. High-temperature-grown AlGaN/AlN intermediate layers and GaN/AlN strained layer superlattice are effective in improving the crystallinity of a following GaN layer and for growing thick device structure on Si, which resulted in obtaining high-breakdown voltage. The AlGaN/GaN HEMT on Si exhibited the breakdown voltage as high as 1402 V with a state-of-the-art figure-of-merit (FOM = BV2/Ron) of 2.6×108 V2Ω-1cm-2.
