    Abstract
  • To figure out the effect of electrode resistivity on the in situ resistivity measurement with four-point probe method in a diamond anvil cell (DAC), the authors simulated the distribution of the steady electric field in the sample with finite element analysis (FEA). It reveals that the electrode resistivity smaller than the sample resistivity too much would result in a large measurement error, and therefore indicates that reducing the resistivity difference between the electrode and sample can improve the measurement accuracy.
