Schematic band diagram of our e-synapse. (a) Under equilibrium, a Schottky barrier is developed at the Au/MoS2 interface and there are traps with trap height ϕt in the MoS2 QD layer. (b) Trapping of electrons in the defects under positive pulses. (c) De-trapping of electrons via hopping and Poole–Frenkel emission under negative pulses.
