Complex spin texture in the pure and Mn-doped topological insulator Bi2Te3.
Topological insulators are characterized by the presence of spin-momentum-locked surface states with Dirac points that span the fundamental bulk band gap. We show by first-principles calculations that the surface state of the insulator Bi2Te3 survives upon moderate Mn doping of the surface layers. The spin texture of both undoped and Mn-doped Bi2Te3 is much more complicated than commonly believ...
متن کاملThe Study of Pure and Mn Doped ZnO Nanocrystals for Gas-sensing Applications
ZnO and ZnO: Mn nanocrystals were synthesized via reverse micelle method. The structural properties of nanocrystals were investigated by XRD. The XRD results indicated that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. Resistive gas sensors were fabricated by providing ohmic contacts on the tablet obtained from compressed nanocrystals powder and the installation ...

A Damascelli ndrea University of British Columbia Entangled spin-orbital texture in topological insulators With their spin-helical metallic surface state, topological insulators define a new state of matter with strong application potential in spintronics. In this talk, I will illustrate how modern spin and electron spectroscopy techniques can be used to reveal the entangled spin-orbital textur...
