Temperature distributions of the electron and lattice systems induced by the Peltier effect have been precisely measured by improved Harman method, where the temperature differences (Delta T-cl and Delta T-la) have been independently evaluated for several terminal lengths (L-V) in thermoelectric materials (Bi,Sb)(2)Te-3. Both temperature distributions have different behaviors in the stationary state, that is, the L-V dependences of Delta T-el and Delta T-la show positive and negative curvatures. respectively. It is also indicated that the temperature difference has a linear relation to L-V in the whole system and the observed non-equilibrium phenomenon is consistent with a law of the conservation of heat quantity.
