2D Te/Mxene Schottky Junction for Self-Powered Broadband Photodetector With High Polarization-Sensitive Imaging The emerging two-dimensional (2D) material Tellurium (Te) is a promising material for polarization-sensitive photodetectors (PDs) due to its narrow bandgap and inherent in-plane anisotropic crystal structure.

Recrystalization of single crystal CsCu2I3 perovskite by I2 treating for enhanced UV detecting abilities Single crystal copper halide perovskites (CsCu2I3) have gained extensive interest since their nontoxic composition and superior ultraviolet (UV) photodetect abilities. However, the surface defects of single crystal CsCu2I3, especially iodine (I) defects, limit its further improvement of photodetecting performance.

Self-powered all-quantum dot based broadband photodetectors for color imaging and heart rate monitoring† Self-powered broadband photodetectors (PDs) are crucial in various daily applications. However, traditional Si-based broadband PDs have limited responses in the infrared and ultraviolet spectra, hindering further development.
