Abstract :
The differences in drain current and drain voltage characteristics of top gate and bottom gate Organic Thin Film Transistor (OTFT) structures are analyzed by two dimensional numerical device simulators. Further discussion shows different characteristics parameters of OTFTs. Transistor based on organic semiconductor (conjugated or conducting polymers) as active layer to manage electric current flow is known as OTFTs. The performance parameters of OTFTs are evaluated from output and transfer characteristics of different structures of OTFTs. Device characteristics parameters have been evaluated in terms of drain current, mobility, on/off current ratio, threshold voltage, subthreshold slope and transconductance. OTFTs are considered as promising device for future development of their various applications in the areas of low-cost and large-area electronics. Further this paper thoroughly discusses the overall performance and applications of OTFTs in various fields.
