CTL based on combined DFT and GW formalism. (a) Schematic description for calculating CTL in the combined DFT and GW formalism, where Erelax is obatined from DFT total energy calculations, and EQP is calculated from GW calculation. The formation energy is a state function, so that the CTL values calcualted following path 1 (P1) or path 2 (P2) result in the same ε(q/q1). (b) Calculated CTL of N-substituted MoS2 from neutral state to negatively charged state as following P1 shown in a.
