众所周知,电阻率和霍耳效应的测量对评价InSb晶体的质量是十分重要的。为能准确、快速地测量这些电学参数,许多人都做了大量工作,特别是科学院上海技术物理研究所、兵器工业部211研究所、电子工业部1411所的一些同志,从测量原理到测试系统的构成都做了许多有益的工作。几年来,结合测试实践,我们在样品接触电极的制作、各电源的配置、测量仪表的选择和样品架的升降等方面,均作了一些改进,先后研制了“晶体接触电极点焊机”、“霍耳效应测试台”及“样品架自动升降”等设备,使测量精度和测试速度都有提高,但是测量系统
It is well known that the measurement of resistivity and Hall effect is very important for evaluating the quality of InSb crystals. In order to accurately and quickly measure these electrical parameters, many people have done a great deal of work, especially the Shanghai Institute of Technical Physics, Institute of Weapons and Technology 211 Institute, Ministry of Electronics Industry 1411 some comrades, from the measurement principle to the test system The composition has done a lot of useful work. Over the past few years, combined with the testing practice, we made some improvements in the production of sample contact electrodes, the configuration of power supplies, the selection of measuring instruments and the lifting of sample racks. We have developed the “crystal contact electrode spot welding machine” “Hall effect test bench” and “sample rack automatically lift” and other equipment, the measurement accuracy and test speed have improved, but the measurement system
