利用金刚石对顶砧装置测量了高压下β-HgS的电导率和霍尔效应，并对其压力作用下的载流子行为进行系统研究.实验结果显示，β-HgS在经历每个相变的同时都伴随着电导率和载流子行为的突变.闪锌矿结构相的β-HgS电导率随压力增加而减小是由载流子浓度和迁移率共同作用的结果，而盐岩矿相的β-HgS的电导率随压力的增加而增加主要是由载流子浓度增加所导致的，并发现在14.6~25.0 GPa范围内是朱砂相和盐岩矿相的两相共存区间.

In this paper,in situ conductivity and Hall effect measurement ofβ-HgS were conducted using diamond anvil cell and the carrier behavior under high pressure was studied systematically. The result showed that the conductivity and carrier behavior changed discontinuously when phase transition occurred. For the zinc blende phase of β-HgS,both the decrease of carrier concentration and mobility led to the decrease of conductivity. For the rock salt phase,the conductivity increase was mainly from the increase of carrier concentration. The cinnabar and rock salt phase coexist in the pressure region of 14. 6~25. 0 GPa.
