摘要
本文用计算机模拟分析了GaAs Hall器件的工作原理,当体内出现静止畴并扩展到Hall器件的电压端时,器件输出阻抗增加,Hall器件的灵敏度相应提高一个数量级;获得高灵敏度的静止畴型的GaAs Hall器件;在实验上证实了这一结果.这种新工作模式的器件将能得到更广泛的应用.
The opration primciple of the stationary domain in GaAs Hall devices has been in-vestigated by using computer simulation.The output impendance of the devices will inc-rease and the sensitivity of Hall devices will be correspondingly enhanced by one order ofmagnitude when the stationary domain occurs n the bulk and extends to the voltage controlterminal.A new Hall device operating at tthe stationary domain model has been fabricatedand the new devices will be widely used
