Low-energy moiré QP band structure of 2° twisted MoS2/WS2 a intrinsic structure, b doped with n = 1 electron per moiré superlattice. c, d Real-space wavefunctions associated with the three lowest conduction bands I, II, and III shown in (a, b), respectively. e Variation of bandwidth in terms of the twist angle. f Variation of bandwidth in terms of the average doping density. The vertical axes in (c, f) are shown in the log scale for clarity.
