Programmable Bandgap in a Topological Semimetal Enables Zero‐Bias UV/NIR Dual Band Photodetection and Optical Encryption Applications

ABSTRACT The monolithic integration of ultraviolet (UV) and near‐infrared (NIR) photodetection in a single device is fundamentally constrained by the inherent spectral crosstalk and architectural complexity of traditional heterostructures. Herein, we circumvent these limitations...
