“…Zn, W, Nb, Fe, Co, Ni, Cu, Ti, V, Ta, Al, and Ga 45,[53][54][55][56][57][58] , and nonmetal dopants includ N, Si, B, N, P, Cl [59][60][61] . However, most of the doping strategies focus on the theoretical calculations based on density functional theory (DFT) [62][63][64][65] , the theoretical results reveal that the doped-MoS 2 sensors perform higher adsorption energy, stronger noncovalent interaction, more carrier transport number, and faster conductivity rate to target gases 60,62,63 .…”
