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…
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…
Surface dominated transport in single crystalline nanoflake devices of topological insulator Bi1.5Sb0.5Te1.8Se1.2
Bin Xia, Peng Ren, Azat Sulaev +3
We report experimental evidence of surface dominated transport in single crystalline nanoflake devices of topological insulator Bi1.5Sb0.5Te1.8Se1.2. The resistivity measurements s…
Anisotropic magnetoresistance in topological insulator Bi1.5Sb0.5Te1.8Se1.2/CoFe heterostructures
B. Xia, P. Ren, Azat Sulaev +4
Topological insulator is composed of an insulating bulk state and time reversal symmetry protected two-dimensional surface states. One of the characteristics of the surface states…
