Ultra-wide spectrum photosynapse array with 64k-scale for neuromorphic fusion imaging - Nature Communications

|
By Guan-Hua Dun, Dan Xie, He Tian, Hua-Jing Fang
| Nature Verified
Abstract Bio-inspired photosynapse hardware with wide spectrum information fusion imaging and neuromorphic processing is promising for complex environments perception. However, integrating ultra-wide spectrum responsivity within a single photosynapse device and scaling to a large array has remained challenging. Here, we demonstrate a 64k-scale (65,536 pixels) ultraviolet-to-mid-infrared photosynapse array based on carbon nanotube/molybdenum oxide heterojunctions.

Electrospun Nanofiber‐Based Synaptic Transistor with Tunable Plasticity for Neuromorphic Computing

|
By Yizhe Guo, Fan Wu, Guan-Hua Dun, Tianrui Cui
| Wiley Online Library Verified
Abstract Biological synapses are the operational connection of the neurons for signal transmission in neuromorphic networks and hardware implementation combined with electrospun 1D nanofibers have realized its functionality for complicated computing tasks in basic three-terminal field-effect transistors with gate-controlled channel conductance.
