What determines the sign of the spin Hall effects in Cu alloys doped with 5d elements?
Zhuo Xu, Bo Gu, Michiyasu Mori +2
We perform a systematical analysis of the spin Hall effect (SHE) in the Cu alloys doped with a series of 5d elements, by the combined approach of density functional theory and Hart…
Analysis of the spin Hall effect in CuIr alloys: Combined approach of density functional theory and Hartree-Fock approximation
Zhuo Xu, Bo Gu, Michiyasu Mori +2
We analyze the spin Hall effect in CuIr alloys in theory by the combined approach of the density functional theory (DFT) and Hartree-Fock (HF) approximation. The SHA is obtained to…
Sign change of the spin Hall effect due to electron correlation in nonmagnetic CuIr alloys
Zhuo Xu, Bo Gu, Michiyasu Mori +2
Recently a positive spin Hall angle (SHA) of 0.021, was observed experimentally in nonmagnetic CuIr alloys [Niimi et al., Phys. Rev. Lett. 106, 126601 (2011)] and attributed predom…
Enhanced spin Hall effect by electron correlations in CuBi alloys
Bo Gu, Zhuo Xu, Michiyasu Mori +2
A recent experiment in CuBi alloys obtained a large spin Hall angle (SHA) of -0.24 (Niimi et al. Phys. Rev. Lett. 109, 156602 (2012)). We find that the SHA can be dramatically enha…
Thermoelectric Properties of Silicon Carbide Nanowires with Nitrogen Dopants and Vacancies
Zhuo Xu, Qing-Rong Zheng, Gang Su
The thermoelectric properties of cubic zincblend silicon carbide nanowires (SiCNWs) with nitrogen impurities and vacancies along [111] direction are theoretically studied by means…
Charged States and Band-Gap Narrowing in Codoped ZnO Nanowires for Enhanced Photoelectrochemical Responses
Zhuo Xu, Qing-Rong Zheng, Gang Su
By means of first-principles calculations within the density functional theory, we study the structural and optical properties of codoped ZnO nanowires and compare them with those…
