| Abstract: | In situ conductivity measurement of AgI under high pressure and ambient temperature was carried out via fabricated microcircuit on diamond anvil cell (DAC). It was observed that conductivity changed with the increasing pressure. The temperature and pressure dependences of conductivity in rs AgI were studied under several pressures at temperatures from 293 K to 443 K. The experimental data show the plot of ln(σT) versus 103T-1 is approximately linear. The ionic carries concentration and activation energy for defect transport were calculated. And also, we investigated the temperature and pressure dependences of conductivity in KOH type AgI and obtained the relation between energy gap and pressure. |
