Phase and amplitude response of "0.7 feature" caused by holes in silicon one-dimensional wires and rings
N. T. Bagraev, N. G. Galkin, W. Gehlhoff +2
We present the findings of the 0.7(2e2/h) feature in the hole quantum conductance staircase that is caused by silicon one-dimensional channels prepared by the split-gate method ins…
Comment on "Experimental Demonstration of the Time Reversal Aharonov-Casher Effect"
Y. Lyanda-Geller, I. A. Shelykh, N. T. Bagraev +1
In a recent Letter, Bergsten and co-authors have studied the resistance oscillations with gate voltage and magnetic field in arrays of semiconductor rings and interpreted the oscil…
Fractional form of the 0.7(2e2/h) feature
N. T. Bagraev, N. G. Galkin, W. Gehlhoff +3
We present the first findings of the spin transistor effect in the Rashba gate-controlled ring embedded in the p-type self-assembled silicon quantum well that is prepared on the n-…
The conductance of the quantum wire touching the gated Aharonov-Bohm ring
I. A. Shelykh, N. T. Bagraev, N. G. Galkin +1
We analyse the conductance of the Aharonov - Bohm (AB) one- dimensional quantum ring touching a quantum wire. The period of the AB oscillations is shown to be dependent strongly on…
The conductance of the gated Aharonov - Bohm ring touching a quantum wire
I. A. Shelykh, N. G. Galkin, N. T. Bagraev
We analyse the conductance of the Aharonov-Bohm one-dimensional quantum ring touching a quantum wire. It is shown that in accordance with experimental data the period of the AB osc…
Quantum point contact with large localized spin: fractional quantization of the ballistic conductance
I. A. Shelykh, N. G. Galkin, N. T. Bagraev
We analyze the conductance of the quantum point contact containing large localized spin J. The additional plateau is formed on a ballistic conductance staircase if only one propaga…
