Hall measurement of MoS₂ and MoTe₂. OM image of a n-MoS₂ and b p-MoTe₂ for four-probe Hall measurement. c Flake thickness profiles of MoS₂ (red) and MoTe₂ (blue) as obtained from AFM scanning, and d R_H(H)–R_H(0) data under the magnetic field (H) for MoS₂ (top negative slopes) and MoTe₂ (positive slope).
