20130052838 | ANNEALING METHOD TO REDUCE DEFECTS OF EPITAXIAL FILMS AND EPITAXIAL FILMS FORMED THEREWITH - An annealing method to reduce defects of epitaxial films and epitaxial films formed therewith. The annealing method includes features as follows: apply a pressure ranged from 10 MPa to 6,000 MPa to an epitaxial film grown on a substrate through a vapor phase deposition process and heat the epitaxial film at a temperature lower than the melting temperature of the epitaxial film. Through applying pressure to the epitaxial film, the lattice strain of the epitaxial film is alleviated, and therefore the defect density of the epitaxial film also decreases. | 02-28-2013 |
20130183625 | PATTERNED GRAPHENE FABRICATION METHOD - A method for fabricating patterned graphene structures, which adopts a photolithographic etching process to fabricate patterned graphene structures, comprises steps: providing a substrate; forming a catalytic layer on the substrate; forming a carbon layer on the catalytic layer; heating the carbon layer to a synthesis temperature to form a graphene layer.

Alternatively, a photolithographic etching process is performed on the carbon layer before heating. Alternatively, a photolithographic etching process is performed on the graphene layer after heating. Compared with the laser etching process, the photolithographic etching process is suitable to fabricate large-area patterned graphene structures and has advantages of high productivity and low cost. | 07-18-2013 |
