Reconfigurable diffusive to drift switching in lead-free Cs2CuBiBr6 memristors with electro-optical synaptic plasticity.
Lead-free halide perovskites, with their optoelectronic properties and environmental compatibility, offer a promising material platform for vision-inspired neuromorphic hardware combining sensing, memory, and computation. We report a multifunctional, lead-free Cs2CuBiBr6 memristive device that combines optical responsi...
