The effect of magnetic impurity scattering on transport in topological insulators
Jesse A. Vaitkus, Cong Son Ho, Jared H. Cole
Charge transport in topological insulators is primarily characterised by so-called topologically projected helical edge states, where charge carriers are correlated in spin and mom…
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-…
Tunable spin and orbital polarization in SrTiO3-based heterostructures
Cong Son Ho, Weilong Kong, Ming Yang +2
We formulate the effective Hamiltonian of Rashba spin-orbit coupling (RSOC) in (LAO/STO) heterostructures. We derive analytical expressions of properties…
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…
Newton's second law in spin-orbit torque
Cong Son Ho, Seng Ghee Tan, Shun-Qing Shen +1
Spin-orbit torque (SOT) refers to the excitation of magnetization dynamics via spin-orbit coupling under the application of a charged current. In this work, we introduce a simple a…
Effect of surface state hybridization on current-induced spin-orbit torque in thin topological insulator films
Cong Son Ho, Yi Wang, Zhuo Bin Siu +3
We investigate the current-induced spin-orbit torque in thin topological insulator (TI) films in the presence of hybridization between the top and bottom surface states. We formula…
