Spin-orbit torque engineering via oxygen manipulation
Xuepeng Qiu, Kulothungasagaran Narayanapillai, Yang Wu +7
Spin transfer torques allow the electrical manipulation of the magnetization at room temperature, which is desirable in spintronic devices such as spin transfer torque memories. Wh…
Graphene terahertz modulators by ionic liquid gating
Yang Wu, Chan La-o-vorakiat, Xuepeng Qiu +7
Graphene based THz modulators are promising due to the conical band structure and high carrier mobility of graphene. Here, we tune the Fermi level of graphene via electrical gating…
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…
Topological Surface States Originated Spin-Orbit Torques in Bi2Se3
Yi Wang, Praveen Deorani, Karan Banerjee +4
Three dimensional topological insulator bismuth selenide (Bi2Se3) is expected to possess strong spin-orbit coupling and spin-textured topological surface states, and thus exhibit a…
