Band Flattening and Landau Level Merging in Strongly-Correlated Two-Dimensional Electron Systems
V. T. Dolgopolov, M. Yu. Melnikov, A. A. Shashkin +1
We review recent experimental results indicating the band flattening and Landau level merging at the chemical potential in strongly-correlated two-dimensional (2D) electron systems…
Spin effect on the low-temperature resistivity maximum in a strongly interacting 2D electron system
A. A. Shashkin, M. Yu. Melnikov, V. T. Dolgopolov +6
The increase in the resistivity with decreasing temperature followed by a drop by more than one order of magnitude is observed on the metallic side near the zero-magnetic-field met…
Valley effects on the fractions in an ultrahigh mobility SiGe/Si/SiGe two-dimensional electron system
V. T. Dolgopolov, M. Yu. Melnikov, A. A. Shashkin +3
We observe minima of the longitudinal resistance corresponding to the quantum Hall effect of composite fermions at quantum numbers , 2, 3, 4, and 6 in an ultraclean strongly i…
Manifestation of strong correlations in transport in ultra-clean SiGe/Si/SiGe quantum wells
A. A. Shashkin, M. Yu. Melnikov, V. T. Dolgopolov +6
We observe that in a strongly interacting two-dimensional electron system in ultra-clean SiGe/Si/SiGe quantum wells, the resistivity on the metallic side near the metal-insulator t…
Two-dimensional system of strongly interacting electrons in silicon (100) structures
V. T. Dolgopolov
Studies of different experimental groups that explore the properties of a two-dimensional electron gas in silicon semiconductor systems ((100) Si metal-oxide-semiconductor field-ef…
Metallic state in a strongly interacting spinless two-valley electron system in two dimensions
M. Yu. Melnikov, A. A. Shashkin, V. T. Dolgopolov +4
We have studied the strongly interacting, two-valley two-dimensional (2D) electron system in ultrahigh mobility SiGe/Si/SiGe quantum wells in parallel magnetic fields strong enough…
