Query: Nanoscale Conductivity Imaging of Correlated Electronic States in
  WSe2/WS2 Moir\'e Superlattices   We report the nanoscale conductivity imaging of correlated electronic states
in angle-aligned WSe2/WS2 heterostructures using microwave impedance
microscopy. The noncontact microwave probe allows us to observe the Mott
insulating state with one hole per moir\'e unit cell that persists for
temperatures up to 150 K, consistent with other characterization techniques. In
addition, we identify for the first time a Mott insulating state at one
electron per moir\'e unit cell. Appreciable inhomogeneity of the correlated
states is directly visualized in the hetero-bilayer region, indicative of local
disorders in the moir\'e superlattice potential or electrostatic doping. Our
work provides important insights on 2D moir\'e systems down to the microscopic
level.
