Spin-resolved electron waiting times in a quantum dot spin valve
Gaomin Tang, Fuming Xu, Shuo Mi +1
We study the electronic waiting time distributions (WTDs) in a non-interacting quantum dot spin valve by varying spin polarization and the noncollinear angle between the magnetizat…
Current partition at zero-line intersection of quantum anomalous Hall topologies
Yafei Ren, Junjie Zeng, Ke Wang +2
At the interface between two-dimensional materials with different topologies, topologically protected one-dimensional states (also named as zero-line modes) arise. Here, we focus o…
Efficient spin-current injection in single-molecule magnet junctions
Haiqing Xie, Fuming Xu, Hujun Jiao +2
We study theoretically spin transport through a single-molecule magnet (SMM) in the sequential and cotunneling regimes, where the SMM is weakly coupled to one ferromagnetic and one…
First-principles study on the electronic and transport properties of periodically nitrogen-doped graphene and carbon nanotube superlattices
Fuming Xu, Zhizhou Yu, Zhirui Gong +1
Prompted by recent reports on graphene superlattices with intrinsic inter-valley interactions, we perform first-principles calculations to investigate th…
Valley Seebeck effect in gate tunable zigzag graphene nanoribbons
Zhizhou Yu, Fuming Xu, Jian Wang
We propose, for the first time, a valley Seebeck effect in gate tunable zigzag graphene nanoribbons as a result of the interplay between thermal gradient and valleytronics. A pure…
Photoinduced valley-polarized current of layered MoS2 by electric tuning
Yunjin Yu, Yanfeng Zhou, Langhui Wan +4
A photoinduced current of a layered MoS2-based transistor is studied from first-principles. Under the illumination of circular polarized light, a valley-polarized current is genera…
Numerical study of parametric pumping current in mesoscopic systems in the presence of magnetic field
Fuming Xu, Yanxia Xing, Jian Wang
We numerically study the parametric pumped current when magnetic field is applied both in the adiabatic and non-adiabatic regimes. In particular, we investigate the nature of pumpe…
Statistical properties of electrochemical capacitance in disordered mesoscopic capacitors
Fuming Xu, Jian Wang
We numerically investigate the statistical properties of electrochemical capacitance in disordered two-dimensional mesoscopic capacitors. Based on the tight-binding Hamiltonian, th…
Transmission spectra and valley processing of graphene and carbon nanotube superlattices with inter-valley coupling
Fuming Xu, Zhizhou Yu, Yafei Ren +3
We numerically investigate the electronic transport properties of graphene nanoribbons and carbon nanotubes with inter-valley coupling, e.g., in \sqrt{3}N \times \sqrt{3}N and 3N \…
