Organic electrochemical transistors (OECTs) have gained significant interest in recent years due to their ability transduce and amplify biochemical signals into easily recorded electrical signals. The magnitude of the amplification offered by an OECT is proportional its transconductance, gm, making gm important figure merit. Much attention has, therefore, been paid materials device geometries, ...

Organic thin-film transistors (OTFTs) are a promising technology for large-area electronics; choosing an appropriate circuit style is critical to enhancing OTFT functionality and reliability.

This study unveils a new tetracene derivative that forms dense, upright monolayers on the surface of aluminum oxide. These monolayers spontaneously self-organize into the active layer in nanoscale field-effect transistor devices when aluminum oxide is used as the dielectric layer. This method gives high yields of working devices that have source-drain distances that are less than 60 nm, thereby...
