摘要：
Spin Seebeck coefficient in a quantum wire is microscopically derived using the Kubo formula and thermal Green's functions, taking account of the effects of disorder in a self-consistent t-matrix approximation. It is found that the induced spin current to be detected through the inverse spin Hall effect will be in the range of experimental detectability when the chemical potential for electrons in the quantum wire is close to the band edge.
