a Phase diagram in B − D space for ν = 2/3 state at T = 1.5 K. GWC stands for generalized Wigner crystal. b Evolution of charge gap with B for ν = 1/2 (D = 0.65 V/nm) and ν = 2/3 (D = 0.57 V/nm) states. The yellow shaded region represents the metallic phase. Error bars reflect the uncertainty in determining the charge gaps. c dV/dI as a function of IDC for ν = 1/2 state with different temperatures under B = 8 T and D = 0.20 V/nm. d dV/dI as a function of IDC for ν = 1/2 state with varied B under T = 1.5 K and D = 0.20 V/nm. e Temperature dependence of Rxx(T) under varied B for ν = 1/2 state (left) and the corresponding scaling plot of the normalized resistivity Rxx(T)/Rc versus T/T0 (right). The inset shows the corresponding T0 vs ∣B − Bc∣. f Scaling analysis for ν = 2/3 state. The determination of the scaling parameter T0, critical magnetic field Bc, and critical resistance Rc are discussed in the main text. The D-value in (c–f) is specially selected at each fractional filling to ensure the observation of melting transitions.
