Abstract
We consider the tunnelling between two monomode quantum wires. We give, in
closed form, the conditions for selective transfer of a single propagating
electron from one wire to the other, leaving all the neighbouring states un
affected. We illustrate the results of the analysis by analytical solutions
for a simple composite system made out of GaAs wires. The electron channel
drop tunnelling in this system is due to one localized state situated with
in a gap of the coupling device. The energy of this state is tuned to be th
at of the Fermi energy.
