dc.description.abstract | We have grown graphene directly on alumina (Al2O3) substrates without catalysts using conventional thermal chemical vapor deposition. By choosing Al2O3 as a growth substrate, the polycrystallinity of graphene was enhanced to form nanometer-size dome-like grains, which ensured a statistically homogeneous electrical property of graphene over a large area. As-grown bilayer, the nanographene (nGr) film showed a sheet resistance of similar to 3 k Omega square(-1) with a standard deviation of similar to 2.3% over 15 mm x 15 mm. Top-and bottom-gate nGr thin film transistors (TFTs) fabricated directly on the Al2O3 substrate exhibited field-effect mobilities of 89 and 41 cm(2) V-1 s(-1), respectively. Moreover, the grown nGr could be easily detached from the Al2O3 substrate due to weak adhesion between the nGr and Al2O3, which has abundant fixed charges. Dry-transfer of the grown nGr from the Al2O3 substrate was realized via spin-coating a polyimide (PI) or poly(4-vinylphenol) film and subsequently detaching the film together with the nGr film. The recycled substrates provided the nGr films with reproducibility. The nGr devices on a 3 mu m-thick PI film were stable upon bending with a bending diameter of down to 6 mm. | - |
