Non-linear antidamping spin-orbit torque originating from intra-band transport on the warped surface of a topological insulator
Yong-Long Zhou, Hou-Jian Duan, Yong-jia Wu +4
Motivated by recent experiments observing a large antidamping spin-orbit torque (SOT) on the surface of a three-dimensional topological insulator, we investigate the origin of the…
Non-linear ballistic response of quantum spin-Hall edge states
Pankaj Bhalla, Ming-Xun Deng, Rui-Qiang Wang +2
Topological edge states exhibit dissipationless transport and electrically-driven topological phase transitions, making them ideal for next-generation transistors that are not cons…
Defect induced negative magnetoresistance and surface state immunity in topological insulator BiSbTeSe2
Karan Banerjee, Jaesung Son, Praveen Deorani +3
Absence of backscattering and occurrence of weak anti-localization are two characteristic features of topological insulators. We find that the introduction of defects results in th…
Gate-tuned quantum oscillations of topological surface states in beta-Ag2Te
Azat Sulaev, Weiguang Zhu, Kie Leong Teo +1
We report the strong experimental evidence of the existence of topological surface states with large electric field tunability and mobility in beta-Ag2Te. Pronounced 2D SdH oscilla…
Temperature-dependent terahertz conductivity of topological insulator BiSbTeSe
Chi Sin Tang, Bin Xia, Xingquan Zhou +3
Using Terahertz Time-Domain Spectroscopy, we study the temperature-dependent complex optical conductivity of the topological insulator, BiSbTeSe sin…
Beta-Ag2Te: A topological insulator with strong anisotropy
Azat Sulaev, Peng Ren, Bin Xia +12
We present evidence of topological surface states in beta-Ag2Te through first-principles calculations and periodic quantum interference effect in single crystalline nanoribbon. Our…
