Abstract

Transport results from measuring ultra-clean two-dimensional systems, containing tunable carrier densities from 7 × 10⁸ cm-² to ~ 1 × 10¹⁰ cm-², reveal a strongly correlated liquid up to rs ≈ 40 where a Wigner crystallization is anticipated. A critical behavior is identified in the proximity of the metal-to-insulator transition. The nonlinear DC responses for r_s > 40 captures hard pinning modes that likely undergo a first order transition into an intermediate phase in the course of melting.
