The values of Jc and Jt of (n)GaN/(p)4H-SiC, (n)GaN/(p)6H-SiC diodes are higher than those of (n)4H-SiC/(p)GaN, (n)6H-SiC/(p)GaN devices respectively, which is due to much wider avalanche zones of the formers, although the values of GAmax, GAn, GAp of materials in the formers close to those of the latters showed in table 2 and figure 1(b).
