Abstract:
1. A method comprising: providing a substrate comprising multiple site-isolated regions on a non-transparent substrate, testing the graphene material in each of the multiple site-isolated regions for a sheet resistance; identifying a first sub-group of the multiple site-isolated regions comprising the graphene materials based on meeting a sheet resistance criterion, transferring said first sub-group of the graphene materials to a transparent substrate; testing the said first sub-group of the graphene materials for transmittance uniformity during a secondary combinatorial screening process, identifying a second sub-group of graphene materials of the multiple site-isolated regions of the first sub-group based on meeting a transmittance uniformity criterion; and integrating said second sub-group of graphene materials into devices and testing said devices for device performance during a tertiary combinatorial screening process.
