Spin-texture inversion in the giant Rashba semiconductor BiTeI
(Nature Publishing, 2016-05)
Semiconductors with strong spin-orbit interaction as the underlying mechanism for the generation of spin-polarized electrons are showing potential for applications in spintronic devices. Unveiling the full spin texture in ...
New generation of two-dimensional spintronic systems realized by coupling of Rashba and Dirac fermions
(Nature Publishing Group, 2015-08-04)
Intriguing phenomena and novel physics predicted for two-dimensional (2D) systems formed by electrons in Dirac or Rashba states motivate an active search for new materials or combinations of the already revealed ones. Being ...
Spin-helical Dirac states in graphene induced by polar-substrate surfaces with giant spin-orbit interaction: a new platform for spintronics
(Nature Publishing Group, 2014-11-04)
Spintronics, or spin electronics, is aimed at efficient control and manipulation of spin degrees of freedom in electron systems. To comply with demands of nowaday spintronics, the studies of electron systems hosting giant ...
Defect and structural imperfection effects on the electronic properties of BiTeI surfaces
(IOP Publishing, 2014-07-24)
The surface electronic structure of the narrow-gap seminconductor BiTeI exhibits a large Rashba-splitting which strongly depends on the surface termination. Here we report on a detailed investigation of the surface morphology ...
