| Outline of Final Research Achievements |
Hot mesh deposition (HMD) method was proposed for large area deposition of a graphene film without catalysts. The decomposition reaction of pentacene, a gas phase polymerization reaction and the mechanism of charge transfer for the graphene on pentacene (GOP) structure were investigated.
The pentacene molecules were decomposed above mesh temperature of 1300 ℃. Main decomposed molecule was the dihydropentacene. When the distance between the mesh and substrate (Dms) was changed, the peak positions of optical absorption spectra changed. Therefore, Dms (the number of gas phase polymerization reactions) influenced on structural property, and the molecular structure of the organic film can be controlled by Dms. The GOP structure is expected as an ultrahigh-frequency-rate modulation device.
