Abstract: A device is provided for depositing carbonaceous structures, for example layers in the form of nanotubes or graphene on a substrate, which is supported by a substrate support disposed in a process chamber housing. A process gas can be delivered onto the substrate through gas outlet openings of a gas inlet element disposed in the process chamber housing. The process chamber housing has two opposing walls which each have holding recesses. At least one plate-shaped component is disposed in the process chamber housing. The plate-shaped component has two edge portions directed away from one another that each are inserted respectively in the holding recess of one of the two opposing walls.

Abstract: A substrate carrier is configured to be arranged in a CVD or PVD reactor, in particular for the deposition of carbon nanotubes or graphene. The substrate carrier has a first broadside surface and a second broadside surface facing away from the first broad-side surface. The first broadside surface and the second broadside surface of the substrate carrier each have a substrate accommodation zone. Fastening elements are provided within each of the substrate accommodation zones to secure a substrate or sections of a substrate to one or more of the broadside surfaces. A CVD reactor is further configured to receive the substrate carrier.
