제목 Effect of curing agent on pin-hole fraction and the dielectric properties of cross-linked gate dielectric layer in organic field effect transistor
초록 Organic field effect transistors (OFET) have been studied actively and the performance of that have improved dramatically over the last decade. As the gate dielectric material, silicon dioxide on silicon substrate has been used widely but with this gate dielectric and substrate, it is impossible to make the flexible electronics. To overcome a disadvantage of this kind of materials, many groups in OFET field have tried to use the solution-based polymer gate materials which can be applied by conventional method such as spin-coating and has the flexible properties.
The thin gate dielectric layer used in OFET must be pin-hole free and have low gate leakage in the range of applied voltage for operating a device. High dielectric constant of the gate dielectric may also become important when low device operating voltage is needed.
In this study, we chose the cross-linked system for the gate dielectric layer with poly-4-vinylphenol (PVP), in which the hydroxyl groups can be cross-linked with a presence of curing agent. With this system, the effect of curing agent on the pin-hole fraction and the dielectric properties of cross-linked gate dielectric layer was studied in detail.
