Photoinduced optical modulation and neuromorphic synaptic functions of BA 2 PbBr 4 perovskite films

Shuo Zhang, Ziye Wu, Qing Hou

An all-optical synapse based on BA 2 PbBr 4 films is demonstrated. 365 nm UV pulses induce reversible transmittance modulation at 404 nm, emulating STM, PPF, and learning-forgetting-relearning. ANN integration achieves 97.31% MNIST classification accuracy.
