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.
