Quantum melting of generalized electron crystal in twisted bilayer MoSe₂.

ABSTRACT: Electrons can form an ordered solid crystal phase ascribed to the interplay between Coulomb repulsion and kinetic energy. Tuning these energy scales can drive a phase transition from electron solid to liquid, i.e., melting of Wigner crystal. Generalized Wigner crystals (GWCs) pinned to moiré superlattices have been reported by optical and scanning-probe-based methods. Using transport measurements to investigate GWCs is vital to a complete characterization, however, still poses a significant challenge due to difficulties in making reliable electrical contacts. Here, we report the electrical transport detection of GWCs at fractional fillings ν = 2/5, 1/2, 3/5, 2/3, 8/9, 10/9, and 4/3 in twisted bilayer MoSe₂. We further observe that these GWCs undergo continuous quantum melting tr
