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…
Spin independence of the strongly enhanced effective mass in ultra-clean SiGe/Si/SiGe two-dimensional electron system
M. Yu. Melnikov, A. A. Shakirov, A. A. Shashkin +3
The effective mass at the Fermi level is measured in the strongly interacting two-dimensional (2D) electron system in ultra-clean SiGe/Si/SiGe quantum wells in the low-temperature…
Spin and valley effects on the quantum phase transition in two dimensions
A. A. Shashkin, S. V. Kravchenko
Using several independent methods, we find that the metal-insulator transition occurs in the strongly-interacting two-valley two-dimensional electron system in ultra-high mobility…
Noise signal as input data in self-organized neural networks
V. Kagalovsky, D. Nemirovsky, S. V. Kravchenko
Self-organizing neural networks are used to analyze uncorrelated white noises of different distribution types (normal, triangular, and uniform). The artificially generated noises a…
