摘要

研究了n-Bi/sub - 2-x/Sb/sub -x/ Te/sub - 3-y-z/Se/sub -y /S/sub -z/组成的多组分固溶体在弱磁场和中磁场中的电磁特性。利用各向同性散射机制,在多谷能谱模型框架下确定了不同固溶体成分和电子浓度的有效质量张量m/sub i//m/sub j/的分量。分析了恒能表面参数对固溶体热电效率的影响。

Galvanomagnetic properties of multicomponent solid solutions based on Bi and Sb chalcogenides
Galvanomagnetic properties of multicomponent solid solutions of n-Bi/sub 2-x/Sb/sub x/Te/sub 3-y-z/Se/sub y/S/sub z/ composition were studied in weak and intermediate magnetic fields. Components of the effective mass tensor m/sub i//m/sub j/ were determined in the framework of the many-valley energy spectrum model using the isotropic scattering mechanism for a variety of solid solution compositions and electron concentrations. The influence of constant-energy surface parameters on the solid solutions thermoelectric efficiency was analyzed.
