Suppression of superconductivity in layered Bi4O4S3 by Ag doping
S. G. Tan, P. Tong, Y. Liu +4
We report X-ray diffraction, magnetization and transport measurements for polycrystalline samples of the new layered superconductor Bi4-xAgxO4S3 (0<x<0.2). The superconducting tran…
Superconducting and thermoelectric properties of new layered Superconductor Bi4O4S3
S. G. Tan, L. J. Li, Y. Liu +4
Polycrystalline sample of the new layered superconductor Bi4O4S3 is successfully synthesized by solid-state reaction method by using Bi, S and Bi2O3 powders with one step reaction.…
Topological charge localization in bilayer graphene induced by an antisymmetric electric potential step
J. C. Martinez, M. B. A. Jalil, S. G. Tan
A charged particle whose energy is less than the electric potential step it is incident upon, is expected to undergo partial reflection and transmission. In bilayer graphene, howev…
Particle-hole Hall effect in graphenelike structures
J. C. Martinez, M. B. A. Jalil, S. G. Tan
We show that a moderately strong constant electric field in the plane of a monolayer graphene sheet can create particle-hole pairs at an observable rate. The pairs undergo zitterbe…
Topological spin-Hall current in waveguided zinc-blende semiconductors with Dresselhaus spin-orbit coupling
T. Fujita, M. B. A. Jalil, S. G. Tan
We describe an intrinsic spin-Hall effect in -type bulk zinc-blende semiconductors with topological origin. When electron transport is confined to a waveguide structure, and the…
Local spin dynamic arising from the non-perturbative SU(2) gauge field of the spin orbit effect
S. G. Tan, M. B. A. Jalil, Xiong-Jun Liu
We use the non-perturbative gauge field approach to study the effects of spin orbit coupling on the dynamic of magnetic moment. We present a general equation of motion (EOM) which…
