Nonpolar Nonvolatile Resistive Switching in Cu Doped $\hbox{ZrO}_{2}$
TL;DR: In this article, the reproducible nonpolar resistive switching behavior is reported in the Cu-doped ZrO2 memory devices, with the sandwiched structure of Cu/ZrO 2:Cu/Pt. The switching mechanism is believed to be related with the formation and rupture of conducting filamentary paths.
Journal ArticleDOI
Resistive switching memory effect of ZrO2 films with Zr+ implanted
TL;DR: In this paper, the authors investigated the impact of implanted Zr+ ions on resistive switching performances of ZrO2-implanted ZRO2 films and found that ZR+ ions exhibit good retention characteristics and high device yield.
Journal ArticleDOI

Xumeng Zhang,Wei Wang,Qi Liu,Xiaolong Zhao,Jinsong Wei,Rongrong Cao,Zhihong Yao,Xiaoli Zhu,Feng Zhang,Hangbing Lv,Shibing Long,Ming Liu +11 more
TL;DR: This letter demonstrates an integration-and-fire artificial neuron based on a Ag/SiO2/Au threshold switching memristor that can realize the basic functions of spiking neurons and has great potential for neuromorphic computing.
Journal ArticleDOI
Vacancy-Induced Synaptic Behavior in 2D WS 2 Nanosheet-Based Memristor for Low-Power Neuromorphic Computing.
Xiaobing Yan,Xiaobing Yan,Qianlong Zhao,Andy Paul Chen,Jianhui Zhao,Zhenyu Zhou,Jingjuan Wang,Hong Wang,Lei Zhang,Xiaoyan Li,Zuoao Xiao,Kaiyang Wang,Cuiya Qin,Gong Wang,Yifei Pei,Hui Li,Deliang Ren,Jingsheng Chen,Qi Liu +18 more
TL;DR: High-performance and low-power consumption memristors based on 2D WS2 with 2H phase are demonstrated, which show fast ON (OFF) switching times, low program current in the ON state, and SET (RESET) energy reaching the level of femtojoules.
Journal ArticleDOI
