Neuromorphic Functions in GaN MOSFET

Artificial intelligence system has developed rapidly in recent years and the key to implement brain-like computing is to find a device which can mimic the biological synapse. In this paper we have propose a novel light-stimulated synaptic transistor using GaN MOSFET structure. The basic synaptic functions like excitatory post synaptic current (EPSC), paired- pulse facilitation (PPF), and short-term memory (STM) have been mimicked. The proposed light-stimulated GaN-based synaptic transistor demonstrates a new implementation method for future artificial intelligence system.
