ABSTRACT

Organic electronics is found in a continuous development owing to discovery of new organic compounds and multiphase materials that exhibit excellent electrical, mechanical, and thermal performance. Among the devices that revolutionized the electronic products one can mention organic thin-film transistors (OTFTs). The chapter attempts to present the current state of art concerning the OTFT parameters, structures and models. A great attention is given to the types of materials utilized in construction of OTFTs, such as dielectrics, semiconductors, conductors, passivation, and substrates. Several aspects that affect the device performance are described, including dielectric properties, scaling of dielectric thickness, processing conditions, contact effects, and environmental stability. The main utility of OTFT devices in the electronic industry and biomedical field is reviewed. The chapter concludes with future research directions that could help to accomplish OTFTs with enhanced functionality.
