a Rxx(Vtg, B⊥) in kΩ at Vbg = 75 V from B⊥ = 8 to 29 T. b Line traces Rxx(Vtg) at B⊥ = 18 and 26 T, respectively. Filling factors are labeled on the corresponding resistance dips (the negative resistance near ν = 4 is due to an instrumental artifact). c Schematics of the resolution sequence of the cyclotron gap Ec, Zeeman gap EZ, and valley gap Ev.
