Amorphous Ga2O3 X-ray Optoelectronic Synapse

Ultrahigh X-ray sensitivity

Built on amorphous Ga2O3 thin film, interfacial oxygen vacancy defects enhance electron tunneling for remarkable X-ray-induced post-synaptic currents, enabling direct integration on commercial TFT arrays for improved image contrast.
