RESONANT-TUNNELING BETWEEN QUANTUM HALL EDGES THROUGH A QUANTUM-DOT

Resonant tunneling between quantum Hall edge states through a quantum dot is discussed in the weak-tunneling limit. For the filling factor v = 1/(2m + 1) (m: integer) the dominant contribution to the resonant c urrent comes from sequential tunneling processes. The height and width of the conductance peaks in the Coulomb blockade oscillations are pro portional to T1/v-2 and T at low temperature T. (C) 1998 Elsevier Scie nce B.V. All rights reserved.
