A More Than Six Orders of Magnitude UV-Responsive Organic Field-Effect Transistor Utilizing a Benzothiophene Semiconductor and Disperse Red 1 for Enhanced Charge Separation

A more than six orders of magnitude UV‐responsive organic field‐effect transistor is developed using a benzothiophene (BTBT) semiconductor and strong donor–acceptor Disperse Red 1 as the traps to enhance charge separation. The device can be returned to its low drain current state by applying a short...

Zusammenfassung:A more than six orders of magnitude UV‐responsive organic field‐effect transistor is developed using a benzothiophene (BTBT) semiconductor and strong donor–acceptor Disperse Red 1 as the traps to enhance charge separation. The device can be returned to its low drain current state by applying a short gate bias, and is completely reversible with excellent stability under ambient conditions.
