A comprehensive first-principle study of borophene-based nano gas sensor with gold electrodes
Yueyue Tian, Houping Yang, Junjun Li +4
Using density functional theory combined with nonequilibrium Green's function method, the transport properties of borophene-based nano gas sensors with gold electrodes are calculat…
Valley-Current Splitter in Minimally Twisted Bilayer Graphene
Tao Hou, Yafei Ren, Yujie Quan +3
We study the electronic transport properties at the intersection of three topological zero-lines as the elementary current partition node that arises in minimally twisted bilayer g…
Mesoscopic Electronic Transport in Twisted Bilayer Graphene
Yulei Han, Yafei Ren, Xinlong Dong +3
We numerically investigate the electronic transport properties between two mesoscopic graphene disks with a twist by employing the density functional theory coupled with non-equili…
Metallic Network of Topological Domain Walls
Tao Hou, Yafei Ren, Yujie Quan +3
We study the electronic and transport properties of a network of domain walls between insulating domains with opposite valley Chern numbers. We find that the network is semi-metall…
Quantum Anomalous Hall Effect in Graphene Proximity Coupled to an Antiferromagnetic Insulator
Zhenhua Qiao, Wei Ren, Hua Chen +4
We propose realizing the quantum anomalous Hall effect by proximity coupling graphene to an antiferromagnetic insulator that provides both broken time-reversal symmetry and spin-or…
Prediction of the Magnetotoroidic Effect from Atomistic Simulations
Wei Ren, L. Bellaiche
An effective Hamiltonian technique is used to investigate the effect of applying curled electric fields on physical properties of stress-free BiFeO3 dots being under open-circuit e…
