The first black‐phosphorus synaptic device is demonstrated , which offers intrinsic anisotropy in its synaptic characteristics directly resulting from its low crystalline symmetry. Key features of biological synapses, such as long‐term plasticity with heterogeneity, including long‐term potentiation/depression and spike‐timing‐dependent plasticity, are mimicked. This demonstration represents an important step toward introducing intrinsic heterogeneity to artificial neuromorphic systems.
