Continuous graphene films synthesized at low temperatures by introducing coronene as nucleation s...
In this paper, we systematically studied the effects of coronene as nucleation seeds for graphene synthesis at low temperatures by chemical vapor deposition. Naphthalene was used as a solid carbon source which is capable of producing graphene at temperatures down to 300 C. The experimental result...[ Learn more ]

Triggering the Continuous Growth of Graphene Toward Millimeter-Sized Grains
A simple but efficient strategy to synthesize millimeter-sized graphene single crystal grains by regulating the supply of reactants in the chemical vapor deposition (CVD) process is demonstrated. Polystyrene is used as a carbon source. Pulse heating on the carbon source is utilized to minimize th...[ Learn more ]

Reconfigurable Terahertz Metamaterials
Reconfigurable anisotropic metamaterials at terahertz frequencies where artificial “atoms” reorient within unit cells in response to an external stimulus has been demonstrated. It is accomplished by fabricating planar arrays of split ring resonators on bimaterial cantilevers designed to bend ou...[ Learn more ]
