Abstract

Ultralow carrier concentrations of two-dimensional holes down to p=1×109cm-2 are realized. Remarkable insulating states are found below a critical density of pc=4×109cm-2 or rs≈40. Sensitive dc V-I measurement as a function of temperature and electric field reveals a two-stage phase transition supporting the melting of a Wigner solid as a two-stage first-order transition.
