WebSep 29, 2024 · Moire superlattices of transition metal dichalcogenide (TMD) bilayers have been shown to host correlated electronic states, which arises from the interplay of emergent moire potential and long-range Coulomb interactions. MoSe2 device p1 for vertical PFM measurements (Fig. 1d,e and Supplementary Figs. 2, 3 and 6) was fabricated by picking up graphite and small-angle-twisted bilayer MoSe2 (targeted at 0.25° twist) with PC on PDMS in sequence. The PC films were peeled off from PDMS and placed onto SiO2 (285 nm)/Si … See more MoSe2 and WSe2 crystals used for device MoSe2 d2, WSe2 d1-d3 and PFM measurement were grown by self-flux growth35.
