Patent ID: 8370096

Claim:
A method for evaluating materials, process conditions, unit processes, and process sequences for graphene production, said method comprising: providing a first substrate and a second substrate, each substrate comprising a predetermined baseline transmittance value at a predetermine wavelength of light; processing regions on said first substrate by combinatorially varying at least one of materials, process conditions, unit processes, and process sequences associated with said graphene production; performing a first characterization test on the processed regions on said first substrate to generate first results; processing regions on a second substrate in a combinatorial manner by varying at least one of materials, process conditions, unit processes, and process sequences associated with said graphene production based on said first results of said first characterization test; performing a second characterization test on the processed regions on said second substrate to generate second results; and determining whether at least one of said first substrate and said second substrate meet a predetermined quality threshold based on said second results.
