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…
Red Emission from Copper-Vacancy Color Centers in Zinc Sulfide Colloidal Nanocrystals
Sarah M. Thompson, Cüneyt Şahin, Shengsong Yang +4
Copper-doped zinc sulfide (ZnS:Cu) exhibits down-conversion luminescence in the UV, visible, and IR regions of the electromagnetic spectrum; the visible red, green, and blue emissi…
Magnon-induced Giant Anomalous Nernst Effect in Single Crystal MnBi
Bin He, Cüneyt Şahin, Stephen R. Boona +4
Thermoelectric modules are a promising approach to energy harvesting and efficient cooling. In addition to the longitudinal Seebeck effect, recently transverse devices utilizing th…
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-…
Fermi Level Dependent Spin Pumping from a Magnetic Insulator into a Topological Insulator
Hailong Wang, James Kally, Cuneyt Sahin +7
Topological spintronics aims to exploit the spin-momentum locking in the helical surface states of topological insulators for spin-orbit torque devices. We address a fundamental qu…
Thermal chiral anomaly in the magnetic-field induced ideal Weyl phase of Bi1-xSbx topological insulators
Dung Vu, Wenjuan Zhang, Cüneyt Şahin +3
The chiral anomaly is the predicted break down of chiral symmetry in a Weyl semimetal with monopoles of opposite chirality when an electric field parallel to a magnetic field is ap…
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…
A high repetition deterministic single ion source
Cihan Sahin, Philipp Geppert, Andreas Müllers +1
We report on a deterministic single ion source with high repetition rate and high fidelity. The source employs a magneto-optical trap, where ultracold Rubidium atoms are photoioniz…
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…
