A field-induced reentrant insulator state of a gap-closed topological insulator (Bi_{1-x}Sb_x) in quantum-limit states
Y. Kinoshita, T. Fujita, R. Kurihara +4
In the extreme quantum limit states under high magnetic fields, enhanced electronic correlation effects can stabilize anomalous quantum states. Using band-tuning with a magnetic fi…
Topological Insulator Cell for Memory and Magnetic Sensor Applications
T. Fujita, M. B. A. Jalil, S. G. Tan
We propose a memory device based on magnetically doped surfaces of 3D topological insulators. Magnetic information stored on the surface is read out via the quantized Hall effect,…
Local spin polarization of Landau levels under Rashba spin-orbit coupling
T. Fujita, M. B. A. Jalil, S. G. Tan +1
We investigate the local spin polarization texture of Landau levels under Rashba spin-orbit coupling in bulk two-dimensional electron gas (2DEG) systems. In order to analyze the sp…
Valley filter in strain engineered graphene
T. Fujita, M. B. A. Jalil, S. G. Tan
We propose a simple, yet highly efficient and robust device for producing valley polarized current in graphene. The device comprises of two distinct components; a region of uniform…
Unified Description of the Intrinsic Spin-Hall Effects
T. Fujita, M. B. A. Jalil, S. G. Tan
The intrinsic spin-Hall effects (SHE) in -doped semiconductors [S. Murakami et al., Science 301, 1348 (2003)] and two-dimensional electron gases with Rashba spin-orbit coupling…
Unified Semi-Classical Description of Intrinsic Spin-Hall Effect in Spintronic, Optical, and Graphene Systems
T. Fujita, M. B. A. Jalil, S. G. Tan
A semi-classical description of the intrinsic spin-Hall effect (SHE) is presented which is relevant for a wide class of systems. A heuristic model for the SHE is developed, startin…
