摘要:
Provided is a method for controlling a device using a doped carbon-nanostructure, and a device including the doped carbon-nanostructure, in which the method for controlling the device selectively controls the mobility of electrons or holes using N-type or P-type doped carbon-nanostructure; the N-type or P-type impurities-doped carbon-nanostructure can selectively control the transport of electrons or holes according to a doped material; and also since the doped carbon-nanostructure limits the transport of charge that is the opposite charge to the transport facilitating charge, it can improve the efficiency of device by adding to a functional layer of device or using as a separate layer in the electrons or holes-only transporting device.

The present invention relates to a 3-dimensional nanostructure having nanomaterials stacked on a graphene substrate; and more specifically, to a 3-dimensional nanostructure having at least one nanomaterial selected from nanotubes, nanowires, nanorods, nanoneedles and nanoparticles grown on a reduced graphene substrate. The present invention enables the achievement of a synergy effect of the 3-dimensional nanostructure hybridizing 1-dimensional nanomaterials and 2-dimensional graphene. The nanostructure according to the present invention is excellent in flexibility and elasticity, and can easily be transferred to any substrate having a non-planar surface. Also, all junctions in nanomaterials, a metal catalyst and a graphene film system form the ohmic electrical contact, which allows the nanostructure to easily be incorporated into a field-emitting device.
