Title: Low-voltage Oxide Transistors for Brain-Inspired Neuromorphic Device Applications

Abstract:

Brain-inspired neuromorphic engineering is becoming a hot topic in the field of information technology. Designing artificial synapses that could emulate essential synaptic plasticities is of great importance for hardware implementation of neuromorphic engineering. Ionic-liquid and ionic-gel electrolyte gated transistors (EGTs) exhibit short-term and long-term changes in channel conductivities. Thus, such devices have strong potential applications in brain-inspired artificial synapse devices and neuromorphic systems. In this talk, recent progresses in our group will be discussed. New achievements will be presented, including the fabrication of low-voltage oxide electric-double-layer transistors, the realization of synaptic responses in the oxide synaptic transistor and the learning abilities for the devices. Moreover, the device demonstrates potential applications in Hodgkin–Huxley artificial synaptic membrane.
