GW correlation effects on plutonium quasiparticle energies: changes in crystal-field splitting
A. N. Chantis, R. C. Albers, A. Svane +1
We present results for the electronic structure of plutonium by using a recently developed quasiparticle self-consistent method (\qsgw). We consider a paramagnetic solution wi…
Detection of the spin character of Fe(001) surface states by scanning tunneling microscopy: A theoretical proposal
Athanasios N. Chantis, Darryl L. Smith, J. Fransson +1
We consider the magnetic structure on the Fe(001) surface and theoretically study the scanning tunneling spectroscopy using a spin-polarized tip (SP-STM). We show that minority-spi…
Theory of electrical spin-detection at a ferromagnet/semiconductor interface
Athanasios N. Chantis, Darryl L. Smith
We present a theoretical model that describes electrical spin-detection at a ferromagnet/semiconductor interface. We show that the sensitivity of the spin detector has strong bias…
Bias-controlled sensitivity of ferromagnet/semiconductor electrical spin detectors
S. A. Crooker, E. Garlid, A. N. Chantis +6
Using Fe/GaAs Schottky tunnel barriers as electrical spin detectors, we show that the magnitude and sign of their spin-detection sensitivities can be widely tuned with the voltage…
Strain-Induced Conduction Band Spin Splitting in GaAs from First Principles Calculations
Athanasios N. Chantis, Manuel Cardona, Niels E. Christensen +5
We use a recently developed self-consistent GW approximation to present first principles calculations of the conduction band spin splitting in GaAs under [110] strain. The spin orb…
Many-body Electronic Structure of Metallic alpha-Uranium
Athanasios N. Chantis, R. C. Albers, M. D. Jones +2
We present results for the electronic structure of alpha uranium using a recently developed quasiparticle self-consistent GW method (QSGW). This is the first time that the f-orbita…
