Single Crystal CVD Graphene on Cu-Sapphire Wafer (II)
Single crystalline CVD graphene film synthesized on single crystalline copper film. The single crystalline copper film is deposited on a sapphire wafer.
Size: 4-inch Wafer
Grade: II
Roughness: < 1 nanometer
Copper film coverage: 80 to 90%
Graphene film coverage: 80 to 90%
Note: Grade II single-crystalline CVD graphene on Cu-Sapphire wafers is primarily for research applications. Dense twinning of copper in low-density and small areas with low graphene coverage may occur within the inscribed rectangular region of the wafer. At the extreme edges of the wafer i.e. outside the inscribed rectangular region of the wafer, uncovered graphene region, dense twinning, and volatilization occurrences may be present.
