High-performance, vertical-type organic transistors with built-in nanotriode arrays

Organic static induction transistors with built-in nanotriode arrays formed in the lateral direction can be fabricated by using a colloidal-lithography technique, avoiding the need to use photolithography. The devices (see figure) demonstrate low operating voltages, high current output, and large trans-conductance, even though they use low-carrier-mobility materials.
