Solid-state Synapse Based on Magnetoelectrically Coupled Memristor
Weichuan Huang, Yue-Wen Fang, Yuewei Yin +8
Brain-inspired computing architectures attempt to emulate the computations performed in the neurons and the synapses in human brain. Memristors with continuously tunable resistance…
A Metal-Insulator Transition of the Buried MnO2 Monolayer in Complex Oxide Heterostructure
Heng-Jui Liu, Jheng-Cyuan Lin, Yue-Wen Fang +15
Functionalities in crystalline materials are determined by 3-dimensional collective interactions of atoms. The confinement of dimensionality in condensed matter provides an exotic…
Nanotube ferroelectric tunnel junctions with giant tunneling electroresistance ratio
Jiu-Long Wang, Yi-Feng Zhao, Wen Xu +4
Low-dimensional ferroelectric tunnel junctions are appealing for the realization of nanoscale nonvolatile memory devices due to their inherent advantage of device miniaturization.…
Lattice dynamics and ferroelectric properties of the nitride perovskite
Yue-Wen Fang, Craig A. J. Fisher, Akihide Kuwabara +5
Using first-principles calculations we examine the crystal structures and phase transitions of nitride perovskite LaWN. Lattice dynamics calculations indicate that the ground-s…
Concepts of super-valley electron and twist induced quantum super-valley Hall effect
Yu-Hao Shen, Jun-Ding Zheng, Chun-Gang Duan
Collective motions of electrons in solids are often conveniently described as the movements of quasiparticles. Here we show that these quasiparticles can be hierarchical. Examples…
Exotic dielectric behaviors induced by pseudo-spin texture in magnetic twisted bilayer
Yu-Hao Shen, Wen-Yi Tong, He Hu +2
Twisted van der Waals bilayers provide an ideal platform to study the electron correlation in solids. Of particular interest is the 30 degree twisted bilayer honeycomb lattice syst…
