Abstract(in English) | We evaluate HOMO-band-edge fluctuation and in-plane crystallite size in pentacene thin-film transistors to clarify an origin of mobility increase by various substrate-surface treatment. By applying the substrate-surface treatments, crystalline domain size increases. However, the HOMO-band-edge fluctuation and the crystallite size do not change by the treatments. On the other hand, when we plot the mobilities against domain sizes, mobility is proportional to the domain size independent of treatments. This results indicate that enhancement of mobility by the treatments is only due to the increase of the size of crystalline domain. |
