Abstract :
In this paper, the influence of surface structure on SiC MESFETs has been studied by investigating electrical characteristics, such as DC, small signal, and large signal characteristics. Three different structures have been fabricated and compared with each other:channel-recessed, gate-recessed, and buried gate structures.
