FIG. 1.

(a) Schematic diagram of the assembly of a resistivity measurement in a DAC. (b) The configuration of a van der Pauw resistivity measurement in a DAC. , , , and denote the electrodes. The solid dark circle represents the insulated gasket wall, and the dashed arc marks the direct contact area between the gasket and the sample (referred as electrical short in the article).

FIG. 2.

The relative error of resistivity introduced by electrical short.

Image of FIG. 3.
FIG. 3.

Electric potential distribution inside the sample. , , , and denote the four electrodes. The arrows indicate the direction of applied electric current. (a) No electrical short between the sample and gasket. (b) Electrical short between the sample and gasket

Image of FIG. 4.
FIG. 4.

Resistivity relative errors vs the distance between the gasket wall to electrodes in the situation of no electrical short and 1/4 area of inner side of gasket shorted.

Image of FIG. 5.
FIG. 5.

ZnS resistivity measurements with the completely insulated gasket (triangles) and the gasket electrically shorted with the sample (hexagons).
