    Abstract: The present invention relates to a graphene film, which is obtainable by a method comprising the steps of: a) providing a substrate, b) epitaxially growing a metal layer on a surface of the substrate, c) optionally increasing the thickness of the metal layer obtained in step b) by growing a metal onto the epitaxially grown metal layer, d) peeling off the metal layer obtained in step b) or optionally in step c) from the substrate and e) depositing graphene onto at least a part of that surface of the metal layer obtained in step d), which was in contact with the substrate before the peeling off conducted in step d). Such a graphene film has a very high charge carrier mobility, namely, when measured on a SiO 2 substrate, of more than 1 1000 cm 2 /V-sec, of at least 15000 cm 2 /V-sec, of at least 20000 cm 2 /V-sec, of at least 25000 cm 2 / V-sec or even of at least 30000 cm 2 /V-sec.

    Abstract: Methods of delaminating a graphene film (60) from a metal substrate (50) are disclosed that substantially preserve the metal substrate. The methods include forming a support layer (80) on the graphene film and then performing an electrochemical process in an electrochemical apparatus (10). The electrochemical process creates gas bubbles (36) at the metal-film interface (64), thereby causing the delamination. The graphene film and support layer form a structure (86) that is collected by a take-up roller (120). The support layer and graphene structure are then separated to obtain the graphene film.

    Abstract: Technologies are generally described for a method and system configured effective to alter a defect area in a layer on a substrate including graphene. An example method may include receiving and heating the layer to produce a heated layer and exposing the heated layer to a first gas to produce a first exposed layer, where the first gas may include an amine. The method may further include exposing the first exposed layer to a first inert gas to produce a second exposed layer and exposing the second exposed layer to a second gas to produce a third exposed layer where the second gas may include an alane or a borane. Exposure of the second exposed layer to the second gas may at least partially alter the defect area.
