Dual-Mode Photodetection and Neuromorphic Memory with PTCDI-C8/C8-BTBT Organic Heterojunctions

Abstract Merging optoelectronic sensing with synaptic emulation is critical for the progression of artificial intelligence. Herein, we report a bias-configurable dual-mode optoelectronic device engineered from a PTCDI-C8/C8-BTBT organic heterojunction, enabling a reversible trans...

Multi-gate organic dendritic transistors for spatiotemporal BCM learning

The Bienenstock–Cooper–Munro (BCM) learning rule effectively mitigates the issue of synaptic weight oversaturation in Hebbian learning via a sliding threshold dependent on historical neuronal activity. However, existing hardware implementations focus primarily on temporal history...

Highly Controllable Polarity in Two-Dimensional Vertical Transistors

Abstract Two-dimensional (2D) vertical transistors, featuring atomically thin channels and an inherent vertical architecture, hold extensive promise for ultrascaled electronics. However, achieving reliable polarity control in such devices has remained a persistent challenge over...

Poleward Redistribution of Tropical Cyclone Hazards over East Asia

Abstract Tropical cyclones (TCs) in the western North Pacific have undergone notable changes over recent decades alongside ocean warming and large-scale atmospheric circulation variability. Using TC best-track data from 1980 to 2025, we identify a pronounced poleward redistributi...
