Sustainable spin current in the time-dependent Rashba system
Cong Son Ho, Mansoor B. A. Jalil, Seng Ghee Tan
The generation of spin current and spin polarization in 2DEG Rashba system is considered, in which the spin-orbital coupling (SOC) is modulated by an ac gate voltage. By using non-…
Zitterbewegung-mediated RKKY coupling in topological insulator thin films
Cong Son Ho, Zhuo Bin Siu, Seng Ghee Tan +1
The dynamics of itinerant electrons in topological insulator (TI) thin films is investigated using a multi-band decomposition approach. We show that the electron trajectory in the…
Resilience of the Spin-Orbit Torque against Geometrical Backscattering
Seng Ghee Tan, Che-Chun Huang, Mansoor B. A. Jalil +2
We show in this paper that the technologically relevant field-like spin-orbit torque shows resilience against the geometrical effect of electron backscattering. As device grows sma…
Perfect valley filter in strained graphene with single barrier region
Can Yesilyurt, Seng Ghee Tan, Gengchiau Liang +1
We present a single barrier system to generate pure valley-polarized current in monolayer graphene. A uniaxial strain is applied within the barrier region, which is delineated by l…
Spin Hall effect in a simple classical picture of spin forces
Seng Ghee Tan, Mansoor B. A. Jalil
Spin Hall effect (SHE) in a 2D-Rashba system has been treated in the spin-dependent precession [J. Sinova et al., Phys. Rev. Letts. 92, 126603 (2004).] and the time-space gauge [T.…
Spin Torque on Magnetic Textures Coupled to the Surface of a Three-Dimensional Topological Insulator
Ji Chen, Mansoor Bin Abdul Jalil, Seng Ghee Tan
We investigate theoretically the spin torque and magnetization dynamic in a thin ferromagnetic (FM) layer with spatially varying magnetization. The FM layer is deposited on the sur…
Electrical modulation of the edge channel transport in topological insulators coupled to ferromagnetic leads
Yuan Li, M. B. A. Jalil, Seng Ghee Tan +1
The counterpropagating edge states of a two-dimensional topological insulator (TI) carry electrons of opposite spins. We investigate the transport properties of edge states in a tw…
Pseudo spin-orbit coupling of Dirac particles in graphene spintronics
S. G. Tan, M. B. A. Jalil, Dax Enshan Koh +2
We study the pseudo spin-orbital (SO) effects experienced by massive Dirac particles in graphene, which can potentially be of a larger magnitude compared to the conventional Rashba…
