Numerical Simulation and Compact Modeling of Organic Thin Film Transistors OTFTs

Abstract

In the last years, there has been a growing interest in Organic semiconductor (OSC) materials newlinethat exhibit semiconductor properties and are composed of organic (carbon-based) molecules newlineor polymers. These materials are crucial in the development of flexible, lightweight, and newlinepotentially low-cost electronic devices. Organic semiconductors can be used in various newlineapplications, including organic light-emitting diodes (OLEDs), organic photovoltaic cells newline(OPVs), and Organic Thin Film Transistors (OTFTs). OTFTs have become an area of research newlineinterest due to their potential use in flexible electronics such as wearable devices, foldable newlinedisplays, and e-paper. These materials can be deposited on flexible substrates at low newlinetemperatures enabling roll-to-roll processing methods. Another benefit of synthetic, polymeric newlinematerials is that their properties can be tailored via the introduction of different chemical newlinegroups that vary overall molecular structures, giving rise to the idea of Make to Order (MTO) newlineelectronics. newlineTo implement a complex circuit on an existing silicon-based EDA (Electronic Design newlineAutomation) tool, a compact model that generates SPICE library is required. This library newlineprovides the necessary device models and parameters that the EDA tool uses to design and also newlinesimulate the circuit accurately. For improving device performance and ensuring accurate newlinesimulations for a variety of OSCs, a deep understanding of device physics is required. These newlinemodels can be simulated on any TCAD (Technology Computer-Aided Design) platform.
