Melting phase diagram of the two-dimensional electron solid in a perpendicular magnetic field
M. Yu. Melnikov, D. G. Smirnov, A. A. Shashkin +3
We determine the thermal melting phase diagram of the electron solid by measuring the onset density of the double-threshold voltage-current curves in the insulating state in the ul…
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…
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…
Triple-top-gate technique for studying the strongly interacting 2D electron systems in heterostructures
M. Yu. Melnikov, A. A. Shashkin, S. -H. Huang +2
We have developed a technique that dramatically reduces the contact resistances and depletes a shunting channel between the contacts outside the Hall bar in ultra-high mobility SiG…
Collective depinning and sliding of a quantum Wigner solid in a 2D electron system
M. Yu. Melnikov, A. A. Shashkin, S. -H. Huang +2
We report the observation of two-threshold voltage-current characteristics accompanied by a peak of broadband current noise between the two threshold voltages in the insulating sta…
