Chapter 2: The chapter concentrates on the powerful instrument in studying the carrier transport properties—thermopower.. Starting with the base theory, the chapter discussed the thermoelectricity phenomenon in metal and semiconductor in detail, including the useful Mott formula, phonon drag effect (normal process and Umklapp process), abnormal thermopower in transition metal, two-band model, magneton scattering, and so on. To resolve the abnormal thermopower in low temperature, some theoretical models, such as the distortion of Fermi surface, resonant scattering, spin-bag model, were argued. Each of them has its limition.

第二章：对热电势这一研究物质载流子输运性质的手段进行了综述，从热电势的原理和基础理论研究开始，针对金属和半导体的热电势现象进行了详细讨论，包括研究工作中常用的Mott公式、声子曳引的正常过程和Umklapp过程、过渡金属异常的热电势现象、双带模型及磁子散射机制等等，对于低温下的异常散射机制讨论了声子曳引、费米面畸变、共振散射机制、自旋口袋模型等若干种理论模型及其局限性。
