Article Synopsis
- This research presents a new design for self-powered photodetectors (PDs) using a combination of SnS nanoflakes and rutile TiO nanorod arrays, creating a II-type heterostructure.
- The device exhibits a unique response to different light wavelengths, generating a positive photocurrent under 385 nm (blocking lower wavelengths) and a negative photocurrent under 410 nm, showcasing its bipolar response.
- This innovation enables dual-band imaging without external filters and implementation of various logical operations (OR, AND, NOT), which could enhance applications like visual systems and secure communications by reducing energy consumption and simplifying design.
