Graphene on Lacey Carbon

The PELCO^® Graphene TEM Support Films are suspended on a lacey carbon film on a 300mesh grid (#01895). The Graphene films we offer have either single, 2, 3-5, or 6-8 ｌayer Graphene sheets and cover the entire TEM grid. The usable area is around 75% due to some unavoidable folds and wrinkles in the Graphene sheets. Graphene, with its unique properties, offers a support film ｌayer that is more conductive and also much thinner than the average carbon support film. Although it is a crystalline support film, its contribution to signal ｆormation is relatively low. This makes the single and 2-ｌayer Graphene support film ideal for high resolution imaging, imaging of nanoparticles and imaging of weak contrast materials/interfaces.

Graphene Specifications
