Abstract The development of vision bionic systems is indispensable for the perception, memory, and processing optical signals, which promotes exploration efficient visual perception systems. In this work, a simple novel two‐terminal optoelectronic memristor based on CuAlAgCr/TiO 2 /W (CTW) structure prepared, where CuAlAgCr high‐entropy alloys are employed as top electrode first time. Before annealing, CTW exhibited fascinating performance, including uniformly distributed operating voltage,...
Recent popularity to realize image recognition by memristor-based neural network hardware systems has been witnessed owing their similarities neurons and synapses. However, the stochastic formation of conductive filaments inside oxide memristor devices inevitably makes them face some drawbacks, represented relatively higher power consumption severer resistance switching variability. In this work, we design fabricate Ag/MXene (Ti <inf xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Center-surround antagonism, a key mechanism in the retina, contributes to encoding of edge contrast rather than overall information on visual image. Here, neuromorphic system consisting multiple ionic devices is built, where each device has lithium cobalt oxide channel arranged common phosphorus oxynitride electrolyte. Because migration Li ions between channels through electrolyte, are highly interactive, as seen with retinal neurons. On basis excitation single and device-to-device...
Phase-change random access memory (PCRAM) has been regarded as one of the most promising candidates for future “universal” due to its mature fabrication techniques and profitable commercialized prospect. To further improve physical performance exploit more application areas, it is imperative develop a physically realistic model that can closely mimic electrical, thermal, phase-change mechanisms PCRAM. Although plenty models have proposed during last two decades, they were constructed from...
Brain-inspired flexible neuromorphic devices are of great significance for next-generation high-efficiency wearable sensing and computing systems. In this paper, we propose a organic electrochemical transistor using poly[(bithiophene)-alternate-(2,5-di(2-octyldodecyl)- 3,6-di(thienyl)-pyrrolyl pyrrolidone)] (DPPT-TT) as the semiconductor poly(methyl methacrylate) (PMMA)/LiClO
Phase-change optical device has recently gained tremendous interest due to its ultra-fast transmitting speed, multiplexing and large bandwidth. However, majority of phase-change devices are only devoted on-chip components such as tensor core main memory, while developing a secondary storage memory in an manner is rarely reported. To address this issue, we propose novel based on plasmonic resonance effects for applications. Such design makes use the dimer nanoantenna generate inside...
Ge2Sb2Se4Te alloy has most recently exhibited its outstanding optical properties for non-volatile photonic storage applications, while electrical and thermal transport were rarely reported, thus limiting application versatility. To overcome the above issue, we performed a detailed systematic study on electrical, mechanical, of using first-principles calculations. The results show that Young's modulus shear are anisotropic, originating from layered crystal structure. Besides, Poisson's ratio...
