The present disclosure relates to a method for making a graphenecarbon nanotube composite structure. The back area electrodes that make contact with the surface of the back of the trunk area are provided in a fitting unit in an exposed state, as well as the trunk area width detection unit. The database may include a textual database andor geometric database. If a calling pattern of a calling telephone number matches a profile of telemarketer communications, the calling number is stored in a database of telephone directory numbers associated with telemarketer communications. A drive assembly is linked to the support and configured to rotate the support about its central axis. A drain is formed in the substrate in a region laterally and vertically offset from the source.
