Claim:
1. An ambipolar synaptic device comprising: an organic semiconductor layer including traps configured for trapping, de-trapping and/or recombination of both electrons and holes; a gate operatively associated with the organic semiconductor layer; a first structure configured for injecting both electrons and holes into the semiconductor layer; an inorganic channel layer; source and drain regions operatively associated with the inorganic channel layer; a first dielectric layer between the organic semiconductor layer and the inorganic channel layer, and a second dielectric layer between the gate and the organic semiconductor layer, the inorganic channel layer and the first dielectric layer being configured such that conductivity of the inorganic channel layer is modulated depending on the polarity and amount of charge stored in the organic semiconductor layer.
