Figure 1. Structural schematics of MXene and MXene heterostructures. (A) Top view of FCC adsorption style in Nb₂CF₂; (B) Side view of FCC adsorption style in Nb₂CT_x; (C) Schematic illustration of ZZ (the orange arrow) and AM (the red arrow) sling directions; (D) Initial sliding configuration of Ti₃C₂T_x/Nb₂CT_x heterostructure showing metal atoms, the metal atoms exactly locate on three distinctive high-symmetry sites within ab plane denoted as A, B and C; (E) Top and side view of high-symmetry sites A, B and C in initial sliding configuration of Ti₃C₂F₂/Nb₂CF₂ heterostructure, where every atom locates on one of three high-symmetry sites without exception. FCC: Face-centered cubic; ZZ: zigzag; AM: armchair.
