SPICE model of organic Junction FETs based on modified charge transport model
Chala Tesfaye, AAiT

Abstract - Organic based devices are getting wider acceptance in current modern electronics technology due to their comparable advantage like flexibility and low cost of fabrication. organic field effect transistors (OFETs) being the core of organic devices, they are becoming current research trends and ongoing research are being done to improve the performance of these devices. To this end, accurate and efficient models that represent the behaviors of OFETs are required. furthermore, circuits simulator like SPICE required a simpler yet accurate model for optimized simulation result. Some models of OFETs have been already reported to describe the device characteristics, but there is still work to be done to improve these models. In this thesis modified charge transportation method for organic material is used as a base to derive a compact model for organic junction field effect transistors. The model is based on inorganic JFET model and incorporate parameters that accounts for observed organic transistor behaviors. The model is developed in Verilog A language to simulate DC output and transfer characters of the transistor..
