Thermopower and weak localization
Semiconductor Science and Technology, 2004We report experiments which demonstrate the effects of weak localization on the thermopower of a low-mobility 2D electron gas at a GaAs/AlxGa1?xAs heterojunction. The measurements rely on the weak-magnetic-field dependence of resistivity and the thermopower characteristic of weak localization. The effects are visible only at temperatures well below 1 K

The thermopower of 99.999% pure, polycrystalline aluminum has been measured from 4.2 to 300\ifmmode^\circ\else\textdegree\fi{}K using Pb as the standard, and from 300 to above 700\ifmmode^\circ\else\textdegree\fi{}K using Au and Cu as alternative standards.

Thermopower in amorphous As2Se3
Physics Letters A, 1972Abstract In the temperature range from 120 to 200°C the thermopower of amorphous As2Se3 varies as S = (k/e) (ES/kT+B) with B = −7.08 and ES = 1.01 ± 0.05 eV, which is the same activation energy as the one obtained from the conductivity curve.

We study theoretically the thermopower in cobalt oxides generalizing the Heikes formula. In the oxides, states of carriers are largely degenerate because the crystalline field and Hund's rule coupling compete in cobalt ions. It is shown that the degeneracy, together with strong correlation of $3d$ electrons, causes the large thermopower.

We calculate the thermopowerSd(T) of spin glasses on the basis of thesd exchange model with additional interactions between the impurity spins by means of time dependent perturbation theory. Similarly to the Kondo effect, the observed giant thermopower can only be explained if one also takes into account the spin independent interactionV between the ...

Diffusion thermopower of metals
Journal of Physics F: Metal Physics, 1974The second order effect of the intrinsic two-phonon processes in the electron-phonon interaction gives rise to a new diffusion thermopower of metals. It is suggested that a higher order electron-phonon scattering process gives an additional term to the diffusion thermopower.

At relatively high temperatures the electron transport in single electron transistors in the Coulomb blockade regime is dominated by the processes of sequential tunneling. However, as the temperature is lowered the cotunneling of electrons becomes the most important mechanism of transport.
