ABSTRACT

IEC TS 62607-6-24:2026 which is a Technical Specification, establishes a standardized method to determine the key control characteristic (KCC)
• number of layer distribution
for CVD graphene film by
• optical contrast measurement
The number of layers and number of layer distribution of CVD graphene film is derived by G‑channel contrast values.
This method is applicable for clean CVD graphene film without twisted multilayer structures on a SiO2/Si substrate.
