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…
