Abstract:
The Aharonov-Bohm effect in submicron rings with narrow electron
channels was studied in the range of magnetic fields from 0 to 15 T and
temperatures from 0.1 to 10 K. It is found that the temperature
dependences of the h/e-oscillation amplitude at low magnetic fields and
in the situation of tunnel-coupled edge current states are different.
The obtained experimental data are explained by the influence of
Fermi-system chirality on the coherent transport in a ring
interferometer. (C) 2004 MAIK "Nauka / Interperiodica".
