Organic field-effect bipolar transistors

Organic field‐effect transistors (FETs) which employ two carefully selected active materials can function as n channel, p channel, or both n‐ and p‐channel devices. It is shown that under an appropriate set of bias conditions the channel current in FETs with α‐hexathienylene (α‐6T) and C60 active layers consist of electron and hole components that are injected from the source and drain contacts into the C60 and α‐6T layers, respectively.
