The Nature of Thermopower in Bipolar Semiconductors
The thermoemf in bipolar semiconductors is calculated. It is shown that it is
necessary to take into account the nonequilibrium distribution of electron and
hole concentrations (Fermi quasilevels of the electrons and holes). We find
that electron and hole electric conductivities of contacts of semiconductor
samples with connecting wires make a substantial contribution to thermoemf.Comment: 17 pages, RevTeX 3.0 macro packag
New physical principles of contact thermoelectric cooling
We suggest a new approach to the theory of the contact thermoelectric cooling
(Peltier effect). The metal-metal, metal-n-type semiconductor, metal-p-type
semiconductor, p-n junction contacts are analyzed. Both degenerate and
non-degenerate electron and hole gases are considered. The role of
recombination in the contact cooling effect is discussed by the first time.Comment: 8 pages, 8 figures, revtex
