We construct the in-plane heterojunctions of Boroβ12/SiC and Graphene/SiC to study the effect of different interface contacts on the electronic properties using first-principle calculations. The metalization of SiC at the contact interface is found in both heterojunctions, and two heterojunctions show high charge inject efficiency. The Boroβ12/SiC possesses p-type Schottky contact, while Graphene/SiC shows n-type Schottky contact. When the electric field is applied to two heterojunctions, the Schottky barrier height and contact type are changed, and the Ohmic contact is achieved at negative electric field. The results propose a way to design planar SiC-based electronic device with tunable interface contact.
