Computer Modeling of Organic Thin Film Transistors (OTFTs) using Verilog-A
Abstract: AbstractOrganic electronics has drawn considerable attention of the researchers with organic thin film transistors (OTFTs) as key components for various applications. Compared to the silicon industry where public models are well defined and commonly used to provide designers with a relative good description of any process, organic devices are still lacking for their complete device models that can fully describe their electrical characteristics. Therefore, compact model development for OTFTs is …
