摘要：
The phonon-drag thermopower, S(gp), is calculated for semiconductor superlattices, with the temperature gradient parallel to the superlattice axis, taking account of electron-phonon Umklapp processes. S(gp) changes sign when the Fermi energy reaches the top of the miniband. The anomalous behaviour is attributed to the inclusion of U-processes.
