Spin Hall conductivity in BiSb as an experimental test of bulk-boundary correspondence
Yongxi Ou, Wilson Yanez-Parreño, Yu-sheng Huang +9
Bulk-boundary correspondence is a foundational principle underlying the electronic band structure and physical behavior of topological quantum materials. Although it has been rigor…
Opposite current-induced spin polarizations in bulk-metallic Bi2Se3 and bulk-insulating Bi2Te2Se topological insulator thin flakes
Jifa Tian, Cüneyt Şahin, Ireneusz Miotkowski +2
One of the most fundamental and exotic properties of 3D topological insulators (TIs) is spin-momentum-locking (SML) of their topological surface states (TSSs), promising for potent…
N-nH complexes in GaAs studied at the atomic scale by cross-sectional scanning tunneling microscopy
D. Tjeertes, T. J. F. Verstijnen, A. Gonzalo +10
Hydrogenation of nitrogen (N) doped GaAs allows for reversible tuning of the bandgap and the creation of site controlled quantum dots through the manipulation of N-nH complexes, N-…
Nanoscale tunnel field effect transistor based on a complex oxide lateral heterostructure
A. Müller, C. Şahin, M. Z. Minhas +2
We demonstrate a tunnel field effect transistor based on a lateral heterostructure patterned from an electron gas. Charge is injected by tunneling from t…
Pancharatnam-Berry phase and kinetic magnetoelectric effect in a three-dimensional helical crystal (Te)
C. Şahin, J. Rou, J. Ma +1
We study the kinetic magnetoelectric effect (current-induced magnetization including both the orbital and spin contributions) in three-dimensional conductors, specializing to the c…
Tunable Giant Spin Hall Conductivities in a Strong Spin-Orbit Semimetal: BiSb
Cüneyt Şahin, Michael E. Flatté
Intrinsic spin Hall conductivities are calculated for strong spin-orbit BiSb semimetals, from the Kubo formula and using Berry curvatures evaluated throughout the Brill…
Derivation of effective spin-orbit Hamiltonians and spin lifetimes, with application to SrTiO heterostructures
Cüneyt Şahin, Giovanni Vignale, Michael E. Flatté
A general approach is derived for constructing an effective spin-orbit Hamiltonian for nonmagnetic materials, which is useful for calculating spin-dependent properties near an arbi…
