Mechanism responsible for initiating room temperature ferromagnetism and spin polarized current in diluted magnetic oxides
Hsiung Chou, Yao-Chung Tsao, G. D. Dwivedi +7
The main obstacles in realizing diluted magnetic oxide (DMO) in spintronics are the unknown electronic structures associated with its high TC ferromagnetism and spin polarized curr…
Origin and Enhancement of Spin Polarization Current in Diluted Magnetic Oxides by Oxygen Vacancies and Nano Grain Size
Hsiung Chou, Kung-Shang Yang, Yao-Chung Tsao +5
Spin polarized current is the main ingredient of diluted magnetic oxides due to its potential manipulation in spintronic devices. However, most research has focused on ferromagneti…
Length and temperature dependent crossover of charge transport across molecular junctions
Ya-Lin Lo, Shih-Jye Sun, Ying-Jer Kao
We study the electronic transport in a molecular junction in which each site is coupled to a local phonon bath using the non-equilibrium Green's function method. We observe the len…
Origin of Ferromagnetism in nitrogen embedded ZnO:N thin films
Chang-Feng Yu, Tzu-Jen Lin, Shih-Jye Sun +1
Nitrogen embedded ZnO:N films prepared by pulsed laser deposition exhibit significant ferromagnetism. The nitrogen ions contained in ZnO confirmed by Secondary Ion Microscopic Spec…
Softening of Spin-Wave Stiffness near the Ferromagnetic Phase Transition in Diluted Magnetic Semiconductors
Shih-Jye Sun, Hsiu-Hau Lin
Employing the self-consistent Green's function approach, we studied the temperature dependence of the spin-wave stiffness in diluted magnetic semiconductors. Note that the Green's…
Spin-Wave Relaxation in Diluted Magnetic Semiconductors within the Self-Consistent Green's Function Approach
J. E. Bunder, Shih-Jye Sun, Hsiu-Hau Lin
We employ a self-consistent Green's function approach to investigate the spin-wave relaxation Γ(p) in diluted magnetic semiconductors. We find the trend of the spin-wave relaxation…
