Quantum Wigner solid in two-dimensional electron systems in semiconductors
Alexander A. Shashkin, Sergey V. Kravchenko
We review recent transport experiments that reveal two-threshold voltage-current characteristics, marked by a significant increase in noise between the two threshold voltages, at l…

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…
