Characteristics of vertical type organic transistor using N-type material and its application for OLED

초록

We have fabricated static induction organic transistor of vertical type in order to improve the problems of conventional organic thin film transistor (OTFT). The vertical type organic transistors were fabricated by using n-type organic semiconductor materials such as F16CuPc, NTCDA and PTCDI C-8. The effects of carrier mobility of organic active materials, the thickness of thin film and gate structure on current-voltage (I-V) and transistor characteristics were investigated. The vertical type organic transistor using PTCDI C-8 exhibited low operation voltage and high on-off ratio. In addition, we have examined the feasibility of application in organic light emitting transistor using a light emitting polymer.
