Spatially Distributed Ramp Reversal Memory in VO₂ (Adv. Electron. Mater. 10/2023)

Memristors Scalable neuromorphic architectures will require a single material as artificial neuron and synapse. The transition metal oxide VO2 is known to spike like a neuron, and has recently shown synapse-like memory upon temperature cycling. In article number 2300085 Alexandre Zimmers and co-workers use new spatially resolved optical contrast measurements to show that surprisingly, synapse-like memory is encoded throughout the entire material.
