• • The MoTe2/SnS2 anti-ambipolar heterojunction achieves a peak-to-valley ratio (PVR) of 465, enabling high-efficiency frequency doubling with minimal distortion, critical for analog signal processing and communication systems.
• • Photodetection spans an ultra-broad wavelength range of 520–2200 nm, covering visible to short-wave infrared, with performance metrics suitable for multispectral imaging and environmental sensing.
• • The device exhibits complete synaptic plasticity, including short-term plasticity (STP), long-term plasticity (LTP), and paired-pulse facilitation (PPF), essential for emulating biological learning rules in neuromorphic hardware.
• • In a reservoir computing (RC) system, the device achieves 98.7% directional recognition accuracy on a vehicle motion dataset, demonstrating its potential for real-time, low-power edge computing applications.
