dc.description.abstract【中文摘要】 介绍了瞬时热电效应法,一种新的实验手段.它基于脉冲激光照射引起的载流子的扩散现象.观测到的瞬时热电电压由光激发导致的传导载流子的扩散形成,并且复合着几个特征的衰减过程指数地衰减.分析这些衰减过程,可以获得载流子的迁移率、有效质量、费密面的变化等重要信息.对瞬时热电效应法的原理以及主要分析方法作了较详细的介绍. 【英文摘要】 Abstract We introduced a new technique called “Transient Thermoelectric Effect (TTE)”, which was based on carrier diffusion as irradiated by a pulsed laser. The observed TTE voltages decayed exponentially with time, showing a multi relaxation process with characteristic relaxation times τ i(i=1,2,3,…) for thermal diffusions of photo induced conduction carriers, analyses of these results could give valuable information about carrier mobilities, effective masses and Fermi surfaces. The principle and the m...zh_CN
