本文利用金刚石对顶砧和集成技术，建立了原位高压霍尔效应测量方法.通过对ZnTe的高压霍尔效应测量，发现在压力的作用下，电导率随压力增加而增加，但是，不同相的电导率随压力增加的机制却是不一样的，对于闪锌矿相的ZnTe，在常压到6.59 GPa范围内，由于载流子浓度和迁移率同时增加引起了电导率随压力增加而增加，但迁移率的增加对电导率增加的影响大于载流子浓度的增加对电导率增加的影响，而在6.59~9.73 GPa范围内，电导率随压力增加而增加的主要原因是载流子浓度随压力的增加所引起，而且朱砂相和Cmcm相的电导率的增加原因同样是由于载流子浓度的增加所引起.

In this paper,in situ Hall effect measurement was conducted using diamond anvil cell and integrated microcircuit. Hall effect of ZnTe under high pressure was investigated. It is found that the conductivity increased with pressure increasing,while the reason of conductivity variation with pressure was different in each phase. For the zinc blende phase(before 6. 59 GPa),both the increase of carrier concentration and the increase of mobility led to the increase of conductivity,and the conductivity increase was mainly from the increase of mobility. In the pressure region of 6. 59~9. 73 GPa,cinnabar phase and Cmcm phase,the increase of the carrier concentration resulted in the conductivity increasing.
