  • Patent number: 10593762
    Abstract: Transferring graphene pieces onto a substrate, by the following steps: a) selecting a substrate comprising a plurality of placeholders for the graphene pieces; b) disposing and aligning the substrate on a substrate holder in a chamber; c) selecting a transfer layer having openings as placeholders for the graphene pieces; d) disposing and aligning the transfer layer on the substrate holder over the substrate so that the openings of the transfer layer are aligned over the placeholders on the substrate; e) adding liquid to the chamber to above the transfer layer, and raising the transfer layer on the liquid column; f) introducing graphene pieces onto the liquid film in the openings of the transfer layer; and g) reducing the distance between the substrate and the graphene pieces until the graphene pieces are disposed on the placeholders of the substrate. A substrate and a device for carrying out the method.
