Chemical Control of Local Doping in Organic Thin-Film Transistors: From Depletion to Enhancement

An organic field‐effect transistor can be switched chemically from depletion (normally on) to enhancement (normally off) mode by inserting a reactive thin layer comprising sulfonyl chloride and sulfonic acid functionalities. Upon exposure of the devices to alkaline gases, such as ammonia, a shift of...

Zusammenfassung:An organic field‐effect transistor can be switched chemically from depletion (normally on) to enhancement (normally off) mode by inserting a reactive thin layer comprising sulfonyl chloride and sulfonic acid functionalities. Upon exposure of the devices to alkaline gases, such as ammonia, a shift of the threshold voltage of up to 60 V is achieved.
