An organic electronic transistor has been developed that possesses the combined long- and short-term potentiation and depression. The principle of operation of the transistor resides at the boundary of field-effect operation and electrochemical switching and has been built up using a thiophene-based trimer as the semiconductor. The trimer can undergo switching of two kinds, a combined feature that represent the fundamental change in synaptic weight at the short and long terms. The switching and modulation of device parameters will be reported in the context of neuromorphic and evolvable computing, especially targeting decision-tree architectures.
