Negative Longitudinal Magneto-Thermoelectric Power in a Semiconductor Parabolic Quantum Well
We present a theoretical study of the electronic thermoelectric power of a
semiconductor parabolic quantum well in a magnetic field. The case of a
longitudinal magnetic field, with respect to the temperature gradient, has been
considered. The calculations were carried out taking into account
spin-splitting of the dimensionally quantized electronic energy levels. It has
been shown that in the region of strong confinement the thermoelectric power
decreases with increasing magnetic field, which is related to the downward
shift of the lower Zeeman-split spin subband.Comment: 11 pages, 1 figire, MISHT-2007 The First International Conference on
