Numerical Simulation and Parameter Analysis for Pentacene based Organic thin Film Transistor with HfO2 Gate DielectricBy Arun Dev Dhar Dwivedi, Pooja Kumari
Abstract: This paper explains 2D numerical simulation and Characterization of Electrical parameter of Pentacene (Organic semiconductor) based Organic thin film transistor (OTFT) devices with HfO2 as a gate dielectric and Electrical parameters including; Threshold Voltage (Vt), Mobility (µ),Ion/Ioff, and Transconductance (gm), Sub threshold slope (SS) are extracted. The numerical simulation includes model for defect density of state and field dependent mobility model.

Modeling and Simulation of Pentacene based Organic Thin Film Transistors with Organic Gate DielectricsBy Pooja Kumari, A.D.D. Dwivedi
Abstract: AbstractTwo structures of pentacene organic thin film transistors (OTFT) with organic dielectrics, polymethyl methacrylate (PMMA) and polyvinyl alcohol (PVA) have been numerically simulated with TCAD ATLAS tool. Output and transfer characteristics were simulated and mobility, threshold voltage, sub threshold swing (SS) and current on/off ratio that play a part in the increment of conductivity of device were extracted. The authors show that the semiconductor-insulator interface actively affects the performance of …
