Dielectric materials for low voltage OFET operation

Organic thin-film transistors are disclosed, as well as process for their manufacture and their use in electronic devices. The organic thin-film transistors comprise a bilayer dielectric formed from a nanocomposite layer and an intermediate capping layer. The organic thin-film transistors operate at very low voltages, allowing their incorporation into portable and wereable devices, as well as apparatuses used in water-sensing applications.
