Inequivalence of the low-density insulating state and quantum Hall insulating states in a strongly correlated two-dimensional electron system
M. Yu. Melnikov, D. G. Smirnov, A. A. Shashkin +3
We find that the behaviors of the voltage-current characteristics as one enters the low-density insulating state and integer quantum Hall insulating states in the ultra-clean two-d…

Stabilization of a two-dimensional quantum electron solid in perpendicular magnetic fields
M. Yu. Melnikov, D. G. Smirnov, A. A. Shashkin +3
We find that the double-threshold voltage-current characteristics in the insulating regime in the ultra-clean two-valley two-dimensional electron system in SiGe/Si/SiGe quantum wel…
