Electric-field-effect thermoelectrics
Journal of Applied Physics, 2001A significantly large thermoelectric “figure of merit” in a bipolar semiconductor is achieved by converting it, by doping, into an essentially monopolar semiconductor. We show here, that for a bipolar semiconductor film, having a thickness smaller than the screening length, there is an alternative to doping to obtain a practically monopolar ...

Journal of the Atmospheric Sciences, 1966
Abstract The electric potential difference under a temperature gradient in ice was measured by the use of single crystal ice, polycrystalline ice including numerous bubbles, and the ice formed from solutions of hydrofluoric acid. At temperatures colder than about −10C, the colder side had positive potential and the H3O+ ion is considered to be the ...

Thermoelectric effect in Aharonov–Bohm structures
Journal of Physics: Condensed Matter, 2014The thermoelectric effects of a single Aharonov-Bohm (SAB) ring and coupled double Aharonov-Bohm (DAB) rings have been investigated on a theoretical basis, taking into account the contributions of both electrons and phonons to the transport process by using the nonequilibrium Green's function technique. The thermoelectric figure of merit of the coupled

Vacancy filling effect in thermoelectric NbO
Journal of Physics: Condensed Matter, 2015Using density functional theory, we have systematically explored the 1a and 1b vacancy filling in NbO (space group Pm-3m) with Nb and N, respectively, to design compounds with large Seebeck coefficients. The most dominating effect was identified for filling of 1b Wyckoff sites with N giving rise to a fivefold increase in the Seebeck coefficient.

Thermoelectric Effects in Superconductors
1981The first measurements of thermoelectricity in superconductors were made by Meissner (1927) who found the Seebeck coefficient S (thermopower) in a superconducting thermocouple to be at least an order of magnitude below the equivalent normal state value.

The effect of thermoelectricity causes the conversion of waste heat into electricity. It is an economical environmentally beneficial and convenient energy conversion technology that can be used across a broad range of temperature. This chapter introduces thermoelectricity while also exploring its historical context.

Thermoelectric effects in superconductors
2007A summary of recent theoretical and experimental work on thermoelectric and related effects in superconductors is given. Whereas this field for a long time was characterized by large discrepancies between theory and experiment, more recent experiments confirm the theoretical concepts.
