Broadband synaptic photoresponse induced by the charged planar Te interlayer in epitaxial Te/GaN hybrid-heterojunction 

Applied Surface Science 705, 1 October 2025, 163492 

Highlights

• Te/GaN hybrid-heterojunction with charged planar Te interlayer has been proposed and realized for broadband synaptic photoresponse.

• Large-scale high-quality Te-GaN(0001) samples were grown by using UHV PVD method.

• Optoelectronic transport measurements confirmed self-powered broadband photoresponse and synaptic plasticity.

• First-principles calculations elucidated that the charged Te layer is induced by the polarization of GaN(0001).
