GRAPHENE BALL STRUCTURE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A graphene ball structure, a manufacturing method thereof, and graphene ball network are provided to be manufactured in a network shape by laminating several graphene ball structures and usefully use lithium ion battery, hydrogen storage device, sensor, capacitor, optical device or electric component etc. CONSTITUTION: A graphene ball structure (100) comprises the core of sphere shape including semiconductor material; a graphene shell (120) including graphene which covers the core. The semiconductor material comprises an IV group semiconductor, III- V group semiconductor or II-VI group semiconductor. The Graphene ball structure is manufactured by chemical vapor deposition using gas including semiconductor material and carbon. The diameter of the core is 1nm ~ 10 μm. The graphene shell has more than one layered structure.
