TCAD SIMULATION AND PERFORMANCE ANALYSIS OF SINGLE AND DUAL GATE OTFTs

This paper presents finite element-based numerical simulation and performance analysis of dual and single gate pentacene-based organic thin film transistors (OTFTs) using technology computer-aided design (TCAD) tools. Electrical characteristics of the devices have been simulated using 2D numerical device simulation software ATLAS (TM) from Silvaco International. Also, device parameters like threshold voltage, mobility, transconductance, subthreshold swing and current on/off ratio of the single and dual gate OTFTs have been extracted and compared.
