Fabrication, Numerical Simulation and Compact Modeling of Ph-BTBT-C10 Organic Thin Film Transistor

Abstract

Flexible and cost-effective electronics have been necessitated by the advent of organic thin-film transistors (OTFTs). This study aims to study the performance of OTFT using a 2-decyl-7-phenyl-[1]benzothieno[3,2-b][1]benzothiophene (Ph-BTBT-C10) organic semiconductor. The paper also explore accurate device modeling for technology optimization and circuit design that supports device improvement. This research includes device fabrication, numerical simulation using TCAD, compact modeling, and parameter extraction. By combining temperature-dependent bandgap narrowing with existing theories, this model can more accurately predict changes in the bandgap with respect to temperature which is critical in designing advanced semiconductor devices. The electrical behaviour of the device can be accurately simulated by refining the other equations related to semiconductors. The experimental data were compared with the results from ATLAS simulations and compact modelling. In addition, the study consists of simulating a P-type TFT-based inverter to evaluate its performance as applied to basic circuit applications using the compact model.
