Abstract :
In present paper, by using the nonequilibrium-Green function approach, we investigated the thermopower through a quantum dot connected to Luttinger liquid. The generally analytic thermopower formula for the thermopower is firstly derived to take into account intralead electron interaction. The thermopower S varies linearly with the temperature T at low temperature and is enhanced by intralead electron interaction. These features qualitatively agree with the experimental and theoretical results.
