Experimental investigation of the edge states structure at fractional filling factors
E. V. Deviatov, V. T. Dolgopolov, A. Lorke +2
We experimentally study electron transport between edge states in the fractional quantum Hall effect regime. We find an anomalous increase of the transport across the 2/3 incompres…
Microwave Response of V3Si Single Crystals: Evidence for Two-Gap Superconductivity
Yu. A. Nefyodov, A. M. Shuvaev, M. R. Trunin
The investigation of the temperature dependences of microwave surface impedance and complex conductivity of V3Si single crystals with different stoichiometry allowed to observe a n…
Microwave response of bulk MgB2 samples of different granularity
A. Agliolo Gallitto, G. Bonsignore, G. Giunchi +2
The microwave response of three high-density bulk MgB2 samples has been investigated in the linear and nonlinear regimes. The three samples, characterized by different mean size of…
Conductivity of a spin-polarized two-dimensional electron liquid in the ballistic regime
A. A. Shashkin, E. V. Deviatov, V. T. Dolgopolov +5
In the ballistic regime, the metallic temperature dependence of the conductivity in a two-dimensional electron system in silicon is found to change non-monotonically with the degre…
