i am using LCR meter to measure resistance of thin film sheet...how i can get the resistivity value?
i have the reading for thickness and resistance..
can somebody help me?
Maybe you can find the answer from the following webpage
What is the relationship between sheet resistance and resistivity

Would you specify the question more precisely.
In particular what is geometry of electrodes on the film that you measure.
The most commonly used is four point probe method with 4 in-line equidistant
electrodes. For such geometry simple formulae between the sheet resistance
of the film and the resistance readout exist. (look on the on web: four-point probe method of the sheet resistance and resistivity measurements).
Resistivity value can be calculated from the following formula:
R=Rb (A/T), where R is resistivity, Rb is bulk resistance, A is area of material and T is thickness of material.
Alternatively, conductivity is inversely proportional to the resistivity=(1/R)
