Abstract

In this paper, we proposed a gate-all-around InAs nanowire field effect transistor (GAA InAs NW FET) that can simulate synaptic behaviors such as short-term potentiation (STP) and long-term potentiation (LTP). The native oxide layer (In2O3) on the surface of InAs NW serves as a charge trapping layer for storing information. The transition from short-term potentiation (STP) to long-term potentiation (LTP) can be achieved by properly adjusting the gate voltage. Due to enhanced gate controllability, the GAA InAs NW FETs are expected to be widely used and promising in neuromorphic systems and networks.
