Abstract(in English) | The electrical properties of n^+-GaN/p^+-SiC heterojunction diodes have been investigated by varying the acceptor concentration of p^+-SiC epilayers (N_a) and polytype of SiC (4H- and 6H-SiC). The current-voltage (I-V) characteristics of diodes with N_a~1x10^<19> cm^<-3> were dominated by tunneling-assisted current. The diodes with N_a~1x10^<18> cm^<-3> exhibit excellent characteristics and 6H-SiC may be a better choice from a view point of electron injection into p-SiC base. Compared to previous investigations (N_a<10^<16> cm^<-3>), we could obtain good rectification with p-SiC doped to two-order-of-magnitude higher acceptor concentration. |
