Bipolar Photoresponse in Graphene/GaN Heterostructure and its Secure Function in Free‐Space Optical Communication (Adv. Electron. Mater. 10/2023)
Source abstract
Abstract
Bipolar Photoresponse In article number 2300243, Xingye Zhou, Shanshan Chen, Xia Guo and co-workers demonstrate an all-in-one bipolar photodetector based on a graphene/GaN heterojunction, which features four stable photocurrent levels and is employed for a secure capability in conventional optical communication. The proposal of a “two keys to one lock” concept presents a new design strategy for photodetectors in information encryption technology.
