IEC TS 62607-6-5:2022

OVERVIEW

IEC TS 62607-6-5:2022(E) establishes a standardized method to determine the key control characteristics

• contact resistance, and


• sheet resistance

for graphene-based materials and other two-dimensional materials by a

• transmission line measurement.

The method uses test structures applied to the 2D material by photolithographic methods consisting of several metal electrodes with increasing spacing between the electrodes. By a measurement of the voltage drop between different pairs of electrodes, sheet resistance and contact resistance can be calculated.

• The method can be applied to any other two-dimensional materials which are subject to electrical metal contact on top of the materials.


• The method provides accurate and reproducible results, if the electrical contact formed between the two-dimensional material and the metal electrodes provides ohmic contact property.
