摘要:

本文从理论上研究了半导体抛物量子阱在磁场中的电子热电势。考虑了纵向磁场与温度梯度的关系。进行计算时考虑了维度量子化电子能级的自旋分裂。结果表明,在强约束区,热电势随磁场的增加而减小,这与低塞曼分裂自旋子带的下移有关。

英文摘要:

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.
