Graphene on Cu foils

Description

Description CVD graphene sheets have been deposited on a 50-micron thick copper foil using a modified chemical vapor technique. In our approach, we pay close attention to engineering defect density and single domain size. Our CVD graphene products undergo routine weekly quality control testing to ensure that the growth system is accurate and parameters are up to date. If your research requires the transfer of graphene to other substrates (SiO2/Si, TEM grids, PET, etc.), please contact us for competitive pricing options.

Features And Benefits

Features And Benefits Our process parameters have been optimized to reduce point defect (vacancy) concentration, increase crystallinity, increase single domain size and reduce 1D grain boundary defect density.

Application

Application Energy storage, catalysis, analytical chemistry, mechanics, adsorption, biology, microelectronics, sensors, etc
