摘要：
Dibenzo[g,p]chrysene (DBC), which belongs to a cyclic aromatic hydrocarbon similar to pentacene, is drawn attention to. DBC is soluble and dissolves in THF, etc. We estimate the crystal structure of DBC by XRD and the morphology of evaporated and spin-coated DBC thin film by atomic force microscope. DBC is used as the active layer of organic thin-film transistor (TFT). The TFT characteristics cannot be obtained in a top contact-type TFT structure, but those can be done in a bottom contact-type TFT structure using SiO2/Si substrate. Unfortunately, the TFT mobility is 10(-5) cm(2)/Vs-order and poorer than that of pentacene TFT because of broken carrier paths between DBC grains and many discrete valleys.
