We first investigated the bare Cr 2 TaC 2 monolayer for the sake of the comparison before applying the biaxial strain to the Cr 2 TaC 2 structure. Figure 1(a) shows the top and side views of the Cr 2 TaC 2 monolayer with the optimized bond lengths. WebFor the biaxial strain from −4% to +6%, the Φ SB,P gradually increases for the graphene/MoS 2 heterostructure, while the Φ SB,N increases initially and then decreases. Moreover, the Φ SB,N is only 0.080 eV under a biaxial strain of +6%, indicating that the Ohmic contact is nearly formed. The results demonstrate the significant effects of a ... hickey sisters salon in saint john nb
