| Abstract(in English) | We have fabricated pentacene organic thin-film transistors(TFTs)using self-assembled monolayers(SAMs)based on alkyl-phosphonic acids with five different alkyl chain lengths as the gate dielectric and investigated the relationship between the SAM chain length and the electrical performance and stability of the transistors. A SAM chain length of 14 carbon atoms provides a maximum TFT mobility of 0.7 cm^2/Vs, along with an on/off current ratio greater than 10^5. According to the results of surface roughness of SAM by using X-ray reflectivity and atomic force microscopy, C14-SAM have most flat surface and the pentacene on C14-SAM have largest grain size of about 3 μm. We also fabricated the large W/L organic TFTs using C14-SAM for realizing low operational voltage and large current TFTs. The On current of the fabricated TFTs showed about 1 mA at 2 V of operational voltage. |
