Room temperature giant and linear magnetoresistance in topological insulator Bi2Te3 nanosheets.
Topological insulators, a new class of condensed matter having bulk insulating states and gapless metallic surface states, have demonstrated fascinating quantum effects. However, the potential practical applications of the topological insulators are still under exploration worldwide. We demonstrate that nanosheets of a Bi(2)Te(3) topological insulator several quintuple layers thick display gian...

Topological insulators exhibit a bulk energy gap and spin-polarized surface states that lead to unique electronic properties1–9, with potential applications in spintronics and quantum information processing. However, transport measurements have typically been dominated by residual bulk charge carriers originating from crystal defects or environmental doping10–12, and these mask the contribution...
متن کاملMagnetoresistance oscillations in topological insulator Bi2Te3 nanoscale antidot arrays.
Nanoscale antidot arrays were fabricated on a single-crystal microflake of topological insulator Bi2Te3. The introduction of antidot arrays significantly increased the resistance of the microflake, yet the temperature dependence of the resistance remains metallic. We observed that small oscillations that are periodic in magnetic field B appeared on top of the weak anti-localization magnetoresis...
متن کاملTopological insulators in Bi2Se3, Bi2Te3 and Sb2Te3 with a single Dirac cone on the surface
Topological insulators are new states of quantum matter in which surface states residing in the bulk insulating gap of such systems are protected by time-reversal symmetry. The study of such states was originally inspired by the robustness to scattering of conducting edge states in quantum Hall systems. Recently, such analogies have resulted in the discovery of topologically protected states in...
متن کاملA spin density wave in the topological insulator Bi2Te3
Topological insulators are materials with a bulk band gap, but with topologically protected, spin polarized surface states with Dirac dispersion. Bi2Te3 is such a topological insulator with a single Dirac cone at the center of the Brillouin zone. ARPES studies have shown that the Fermi surface of Bi2Te3 changes from a circle to a hexagon, and then to a hexagram, when moving away from the Dirac ...
