Neuromorphic Logical Transformation Based on Wafer-scale Synaptic Phototransistor Array

A synaptic phototransistor array achieved neuromorphic logical transformation based on 10cm diameter (4 inches) wafer scale IGZO synthesized by magnetron sputtering. The phototransistor in array had significantly favorable optoelectronic performance, which reached ~ 10
