, enabling real-time, on-chip image processing even under dim-light conditions. This functionality is further utilized for noise reduction in traffic-light images prior to object detection with YOLOv11 network, establishing a direct bridge between device-level photodetection and machine-learning-driven recognition. This interfacial lattice distortion engineering paradigm in van der Waals-contacted 2D devices opens new avenues for designing ultrasensitive, low-noise, and functionally integrated optoelectronic devices.
