Hybrid nanoparticle-organic transistor mimics a synapse
Nanotechnology researchers in France have developed a hybrid transistor called NOMFET (Nanoparticle Organic Memory Field-Effect Transistor) that shows the main behavior of a biological spiking synapse and can lead to a new generation of neuro-inspired computers, capable of responding in a manner similar to the nervous system. The organic device is made of a molecule called pentacene (an organic semiconductor) and gold nano-particles.
“Basically, we have demonstrated that electric charges flowing through a mixture of an organic semiconductor and metallic nanoparticles can behave the same way as neurotransmitters through a synaptic connection in the brain,” Dominique Vuillaume, a research director at CNRS and head of the Molecular Nanostructures & Devices group at the Institute for Electronics Microelectronics and Nanotechnology (IEMN) tells Nanowerk.
