Method of measuring the surface resistivity of semiconducting tapes
Material: Perform this test on a clean unused sample of semi-conducting tape. Method: Clamp a length of tape between the electrodes (see
Figure C.1), ensuring that the tape is connected at right angles to the electrodes with just enough tension to prevent a sag in the tape. Adjust
the d.c. power supply to produce a reading of approximately 1 mA on the ammeter and note the voltage indicated on the voltmeter. Using a graduated scale, measure the width of the tape and its length between the voltage electrodes. Calculation: Calculate the surface resistivity ρ (ohms per mm/mm) of
the semi-conducting tape from the equation,
