Signatures of topology in ballistic bulk transport of HgTe quantum wells
E. G. Novik, P. Recher, E. M. Hankiewicz +1
We calculate bulk transport properties of two-dimensional topological insulators based on HgTe quantum wells in the ballistic regime. Interestingly, we find that the conductance an…
Side-jumps in the spin-Hall effect: construction of the Boltzmann collision integral
Dimitrie Culcer, E. M. Hankiewicz, Giovanni Vignale +1
We present a systematic derivation of the side-jump contribution to the spin-Hall current in systems without band structure spin-orbit interactions, focusing on the construction of…
Ballistic quantum spin Hall state and enhanced edge backscattering in strong magnetic fields
G. Tkachov, E. M. Hankiewicz
The quantum spin Hall (QSH) state, observed in a zero magnetic field in HgTe quantum wells, respects the time-reversal symmetry and is distinct from quantum Hall (QH) states. We sh…
Spin-Hall effect and spin-Coulomb drag in doped semiconductors
E. M. Hankiewicz, G. Vignale
In this review, we describe in detail two important spin-transport phenomena: the extrinsic spin-Hall effect (coming from spin-orbit interactions between electrons and impurities)…
