All the previous homogeneous theories result in which are at variance with the experimental data. It is for this reason, previous theories have consistently used experimental value of in calculating thermopower tensor . The inhomogeneous and non-equi

The phonon drag and electron diffusion contribution to the tensor which determines the heat flux is calculated for a silicon MOSFETS in a perpendicular magnetic field . We used nearly the same theoretical formalism as Ref. [6], but improvements are m

For a 2DEG in a Si MOSFET the important scattering mechanisms at low temperatures are remote impurity, background impurity and interface roughness scattering. The authors perform a detailed calculation of the energy dependence of each scattering mech

The authors present the first observations of rectification fluctuations in a mesoscopic conductor; a small n+-GaAs wire. The results obtained enable them to examine directly that part of the conductance fluctuation that is antisymmetric in the appli

New accurate results for the thermopower of Si inversion layers are compared with the calculated screened phonon-drag thermopower. Good agreement is obtained for both the temperature dependence and the magnitude, except at the lowest temperatures, wh

We have measured the thermopower of small ${\mathit{n}}^{+}$-GaAs wires using a novel electron heating technique. The results show very large fluctuations which are in good agreement with existing theories. We believe this to be the first observation
