变温霍耳测量系统是研究固体输运性质的最重要手段之一。特别是在评价半导体材料的载流子类型、浓度和迁移率时,是其他实验方法不可代替的。变温霍耳效应对于杂质电离能的测量,在与光学方法(如长波光电导或光吸收等)测量结果有出入时,优先被物理学家所引用。随着计算机的发展,美国等发达国家从70年代开始至今,一直在竞先研究自动霍耳测试系统,并逐渐商品化。以美国KEITHLEY公司为例,1978年开始研制出System2(S2),1981年研制出HallⅢ,1984年研制出System100(S100)。 Variable temperature Hall measurement system is one of the most important means to study the nature of solid transport. Especially in the evaluation of semiconductor material carrier type, concentration and mobility, and other experimental methods can not be replaced. Variable temperature Hall effect ionization energy for the measurement of impurities, and optical methods (such as long-wave photoconductivity or light absorption, etc.) are different from the measurement results, priority physicists are cited. With the development of computers, the developed countries such as the United States have been studying the automatic Hall-Ear test system and gradually commercialized since the 1970s. In the United States KEITHLEY company, for example, in 1978 began to develop System2 (S2), 1981 developed Hall Ⅲ, 1984 developed the System100 (S100).
