"NettetThese features signify the correlated gaps in the WSe 2 /WS 2 Mott insulator state at n=1 as well as the generalized Wigner crystal insulator states at n=1/3, 1/2, 2/3. This is due to the fact that the correlated gaps make the WSe 2 /WS 2 heterostructure electronically incompressible and so electrons are electrostatically forced into the graphene sensing … " - Mott and generalized wigner crystal
