ChangchunOne chip senses, stores and processes light at 300°C.
In-sensor computing skips moving raw data between detectors, memory and processors.
Layers of aluminium gallium nitride create opposite polarized charges at interfaces, separating electrons from holes so light is stored as trapped holes.
The Nature Materials study tested single devices and a small array, and the image-classification result is a simulation.
System-level energy use, integration density and manufacturing yield still need testing in larger hardware.

- details the AlGaN device's nanowatt-level light sensing and 300°C stability, arguing III-nitride supply chains make it easier to scale than 2D materials
