Organic Field-Effect Transistors (OFETs)

Dear Colleagues,

Since the fabrication of the first Organic Field-Effect Transistor (OFET) in 1986, researchers’ interest to develop and improve OFET technology has grown exponentially. A remarkable example is the outstanding work conducted by the scientific community to increase the mobility of said technology to above 10 cm²/Vs.

Nowadays, OFETs can be exploited in a wide range of applications, from academic research activities to their commercial implementation targeting OFETs’ distinctive properties and low-cost fabrications. Moreover, several other devices directly originate from OFET technology, among which OFET-based sensors represent a disruptive innovation in the field. This was possibly thanks to the specific properties of organic semiconductors, such as the possibility to tune the electro-chemical properties of the materials and the low-temperature fabrication processes (e.g., ink-jet printing, slot-die …) that opened the door to a new paradigm for the development of flexible and wearable electronics.

Despite all these achievements, some drawbacks are still unsolved. A few examples are the large disparities between p-type and n-type OFETs (both in terms of performance and number of available materials) and the devices’ reliability, which is still poor compared to silicon and III-V semiconductors. To significantly improve OFET theory, these are important aspects that need to be tackled by keep investing on the development of new materials, on the innovation of OFETs fabrication processes, and on the design on novel architectures.

This Special Issue aims at collecting those contributions covering the latest research in the field of Organic Field-Effect Transistors. We are looking for manuscripts exploiting the use of new deposition processes and materials for OFET fabrication, as well as for articles investigating devices characterization, physics, and reliability.
