a and b ρxx and ν = (h/e2)/ρxy as functions of proximity gate voltage at different B from 6 to 12 T. Vertical arrows indicate minima in ρxx. Horizontal dashed lines mark emerging Hall plateaus for ν = 2/3 and 5/3. c Map of ρxx as a function of B and proximity gate voltage. Numbers indicate different filling factors with red lines serving as guides to the eye.
