摘要:
We investigate the thermoelectric transport properties of the Luttinger liquid coupled to the quantum dot by tunnel junctions. A general thermopower expression is derived by using nonequilibrium Green function method. At low temperature the thermopower is of linear temperature dependence and conductance is of a temperature-dependent power-law behavior. There is a peak in the curve of the thermopower vs. gate voltage. Intralead electron interaction enhances thermopower at low temperatures and the large slope is interpreted as a character of the Luttinger liquid. In the limit of strong electron interaction thermopower S(T) at low temperature can be represented by the noninteracting electrons S-0(T) as: S(T) = 3S(0)(T)/(2g).
