Modiffied Schottky emission to explain thickness dependence and slow depolarization in BaTiO nanowires
Y. Qi, J. M. P. Martirez, Wissam A. Saidi +4
We investigate the origin of the depolarization rates in ultrathin adsorbate-stabilized ferroelectric wires. By applying density functional theory calculations and analytic modelin…
Validity of Equation-of-Motion Approach to Kondo Problem in the Large- limit
Yunong Qi, Jian-Xin Zhu, C. S. Ting
The Anderson impurity model for Kondo problem is investigated for arbitrary orbit-spin degeneracy of the magnetic impurity by the equation of motion method (EOM). By employing…
Unusual giant magnetoresistance effect in heterojunction structure of ultra-thin single-crystal Pb film on silicon substrate
Jian Wang, Xu-Cun Ma, Yun Qi +7
Superconductor films on semiconductor substrates draw much attention recently since the derived superconductor-based electronics have been shown promising for future data process a…
Kondo Resonance in the Presence of Spin-Polarized Currents
Yunong Qi, Jian-Xin Zhu, Shufeng Zhang +1
We propose an improved method of the equation of motion approach to study the Kondo problem in spin-dependent non-equilibrium conditions. We find that the previously introduced add…
Current-induced spin polarization in nonmagnetic semiconductor junctions
Yunong Qi, Michael E. Flatté
Spontaneous spin polarization of the electrical current flowing through nonmagnetic semiconductor junctions can be generated by carrier scattering processes that are independent of…
Spin Gunn Effect
Yunong Qi, Zhi-Gang Yu, Michael E. Flatté
We predict that the flow of unpolarized current in electron-doped GaAs and InP at room temperature is unstable at high electric fields to the dynamic formation of spin-polarized cu…
