Monolithically Integrated IGZO Synaptic Transistors on a Silicon Nitride Waveguide for Optoelectronic Neuromorphic Computing

Abstract We report the first demonstration of monolithically integrated amorphous indium–gallium–zinc oxide (IGZO) synaptic transistors on a silicon nitride (Si3N4) waveguide, enabling direct on-chip optical programming by using guided 532 nm light. In this architecture, the evan...

Direct Observation of Topologically Enhanced Interfacial Miscibility in Ring–Linear Polymers

Abstract Cyclic polymers, lacking chain ends, exhibit unique behavior when blended with linear analogues. In such cyclic/linear mixtures, cyclic polymers permit chain threading, wherein linear chains penetrate the ring-like structure, increasing entropy and enhancing interfacial...
