it is circular pellet of thickness 0.6mm and diameter 13mm.

i understood what you are trying to convey! it is circular disk shaped sample of thickness of 1mm or so. The resistivity of the sample is very high, so we preferred to measure using two probe method. There are formulas for vanderpauw, collinear four probe configurations to calculate the...

thanks for the reply... I measured the dc resistance already,but how to calculate the resistivity for a circular sample. Using two probe method.

Hai, I am doing my masters degree in physics. can somebody help me in which formula to use for calculating resistivity of a sample of circular shape using two probe measurements, which should include thickness and correction factor also. Thank You!
