DFT calculations for H-terminated SiC 64-ZNR with a kink-type domain wall. (a,a1,a2) Both edges consist of carbon as shown in Fig. 1a. (b,b1,b2) Both edges consist of silicon as shown in Fig. 1b. (a,b) Show the band structures. (a1,b1) Show ∣Ψ∣2 at EF. (a2,b2) show schematics for the propagating states at EF. The up and down arrows correspond to the opposite propagating directions. The solid and dashed arrows represent the opposite valleys.
