Tunable ohmic van der Waals-type contacts in monolayer C₃N field-effect transistors.

ABSTRACT: Monolayer (ML) C₃N, a novel two-dimensional flat crystalline material with a suitable bandgap and excellent carrier mobility, is a prospective channel material candidate for next-generation field-effect transistors (FETs). The contact properties of ML C₃N-metal interfaces based on FETs have been comprehensively investigated with metal electrodes (graphene, Ti₂C(OH/F)₂, Zr₂C(OH/F)₂, Au, Ni, Pd, and Pt) by employing ab initio electronic structure calculations and quantum transport simulations. The contact properties of ML C₃N are isotropic along the armchair and zigzag directions except for the case of Au. ML C₃N establishes vertical van der Waals-type ohmic contacts with all the calculated metals
