▎ 摘　　要

NOVELTY - The composite structure (400) comprises a first graphene (421), a second graphene (422) separated apart from the first graphene, an one-dimensional nanostructure (410) disposed between the first graphene and the second graphene, and a substrate on which the graphenes is disposed. The nanostructure: is electrically connected to the first and second graphenes; is disposed perpendicularly to and/or disposed inclined with respect to the first and second graphenes; consists of nanowires, nanotubes and/or nanorods; and comprises a material consisting of a IV group semiconductor. USE - The composite structure is useful in a logic device, a memory device, a supercapacitor, a sensor, an optical device, an energy storage device, flexible and stretchable device, a transparent display device or other similar applications. ADVANTAGE - The composite structure has high flexibility, improved electrical and thermal conductivity, enhanced mechanical strength and excellent elastic characteristics.
