Outline of Final Research Achievements

We tried to form the graphene film on a quartz substrate using pentacene (C22H14) molecules including a hexagonal lattice. To enhance the pentacene decomposition and graphene formation, the two W catalysts were used. The pentacene dimer (peripentacene) was obtained from pentacene using two heated catalysts. The W supported Ni (WNi) mesh was used as a catalyst to supply the decomposition site (Ni region) and polymerization site (W region) of the pentacene molecules. The decomposition temperature of pentacene molecules for the WNi(100%) mesh was lower than that for the W mesh. The pentacene multimers (N=2-5) were obtained and polymerization reaction can be enhanced by using the WNi(3%).
