Thermoelectric phenomena in ferrofluids
The application of a temperature difference (∆T) across a solid conductor causes mobile charge carriers to diffuse from hot to cold regions, giving rise to a thermoelectric voltage ∆V=-Se. ∆T. The prefactor Se is called the thermopower or Seebeck coefficient which describes how electrical energy can be generated from the thermal energy. The great majority of today’s thermoelectric (TE) research...
متن کاملThermodynamics of Thermoelectric Phenomena and
Fifty years ago, the optimization of thermoelectric devices was analyzed by considering the relation between optimal performances and local entropy production. Entropy is produced by the irreversible processes in thermoelectric devices. If these processes could be eliminated, entropy production would be reduced to zero, and the limiting Carnot efficiency or coefficient of performance would be o...
متن کاملTime and frequency resolved dynamics of ArBr2.
We report the first spectroscopic observation of and vibrational predissociation dynamics for ArBr(2). Measurements are reported for the linear and T-shaped isomers with time and frequency resolution near the Fourier limit of a 15 ps pulse. For the T-shaped isomer, the Ar-Br(2) bond energy D(0) for the B state, nu(')=19, is found to be 200 cm(-1), yielding a D(0)(X) value of 213 cm(-1). Product...
متن کاملDensity-functional theory of thermoelectric phenomena.
We introduce a nonequilibrium density-functional theory of local temperature and associated local energy density that is suited for the study of thermoelectric phenomena. The theory rests on a local temperature field coupled to the energy-density operator. We identify the excess-energy density, in addition to the particle density, as the basic variable, which is reproduced by an effective nonin...
