Working principle and calculation formula

The calculation and testing principle of the square resistance of thin layer samples using the dual electric measurement four probe method are as follows

：

The layout of the linear four probe test is shown in Figure 8, with adjacent needle distances of S1, S2, and S3. Based on physical and electrical principles:

When the current passes through probes 1 and 4, and probes 2 and 3 test the voltage, the calculation is as follows:
