Paper Abstract

In this paper we developed an optimized process conditions of poly(4-vinylphenol) (PVP) as an organic gate compatible to polyethylene terephthalate(PET) substrate by varying the density of each component of PVP gate and also baking temperature. Pentacene TFTs were fabricated by the above obtained process and the performance was examined to find out the mobility of 0.7±0.2 cm2/V·sec and on/off current ratio of 106 and sub-threshold slope of 0.27V/dec, which can be applicable to drive an organic LED. In addition the inverters made on PET substrate provided the gain of 9 and exhibited the minor hysteresis which means the low interface states.
