摘要
The mechanism of pentacene molecule decomposition by a heated tungsten (W) mesh in H-2 atmosphere is investigated for the development of an organic-thin-film deposition method. In this method, pentacene molecules come in contact with a heated W mesh before reaching the substrate in H-2 atmosphere. The decomposition reaction occurs notably above 1300 degrees C. The decomposed precursors were identified to be dihydropentacene, p-distrylbenzene, and 2,2%26apos;-dimethyl-1,1%26apos;-binaphthalene. On the other hand, the pentacene molecules did not decompose at 1400 degrees C in He atmosphere. It is found that H-2 affects the decomposition reaction of pentacene molecules. These decomposed precursors are expected as a source of large graphene sheets and graphene nanoribbons.
