Effect of short-range impurities on low-temperature conductance and thermopower of
quantum wires

(Dated: February 2, 2008)
7 The electron transport through the parabolic quantum wire placed in longitudinal magnetic field
0 in the presence of the system of short-range impurities inside the wire is investigated. Using approach
0 based on the zero-range potential theory we obtained an exact formula for the transmission coefficient
2 of the electron through the wire that allows to calculate such the transport characteristics as the
c conductance and differential thermopower. The dependencies of conductance and thermopower on
e the chemical potential and magnetic field are investigated. The effect of elastic scattering due to
D short-range impurities on low-temperature conductance and thermopower is studied. It was shown
that the character of the electron transport essentially depends on the position of the every scattering
0 center. The presence even isolated impurity leads to destruction of conductance quantization. In
3 some cases it is possible that thermopower can change the sign in dependence on chemical potential
and magnetic field.
