제목 Characteristics of Vertical Organic Transistors with Nano-Patterned Gate using Monodispersed Colloidal Spheres and Block Copolymer
초록 We have fabricated vertical organic transistors consisting of nano patterned gate using self-assembly of block copolymer and studied on device characteristics. The gate opening size of device made by new method was 30 ~ 40 nm. The device was compared with that having 200 nm opening size gates which is fabricated using monodispersed colloidal polystyrene spheres. The device using block copolymer showed improved performance in terms of on-off ratio. We have also fabricated transistors with tungsten oxide buffer layer to increase the on current of the device. The devices were investigated from the measurements of current-voltage characteristics and impedance spectroscopy and atomic force microscope (AFM) and scanning electron microscope (SEM) images.
