Electronic structure and transport properties of La_0.7Ce_0.3MnO_3
W. J. Chang, J. Y. Tsai, H. -T. Jeng +9
X-ray absorption spectroscopy (XAS), optical reflectance spectroscopy, and the Hall effect measurements were used to investigate the electronic structure in La_0.7Ce_0.3MnO_3 thin…
Tuning of coupling modes in laterally parallel double open quantum dots
Chi-Shung Tang, Wing Wa Yu, Vidar Gudmundsson
We consider electronic transport through laterally parallel double open quantum dots embedded in a quantum wire in a perpendicular magnetic field. The coupling modes of the dots ar…
A state with negative binding energy induced by coherent transport in a quantum wire
Vidar Gudmundsson, Chi-Shung Tang, Andrei Manolescu
In a two-dimensional quantum wire in a perpendicular magnetic field with a smooth embedded repulsive scattering potential we find in the multimode conductance resonances caused by…
Strain-Induced Coupling of Spin Current to Nanomechanical Oscillations
A. G. Mal'shukov, C. S. Tang, C. S. Chu +1
We propose a setup which allows to couple the electron spin degree of freedom to the mechanical motions of a nanomechanical system not involving any of the ferromagnetic components…
Transport through a quantum ring, a dot and a barrier embedded in a nanowire in magnetic field
Vidar Gudmundsson, Yu-Yu Lin, Chi-Shung Tang +3
We investigate the transport through a quantum ring, a dot and a barrier embedded in a nanowire in a homogeneous perpendicular magnetic field. To be able to treat scattering potent…
Generation of spin current and polarization under dynamic gate control of spin-orbit interaction in low-dimensional semiconductor systems
C. S. Tang, A. G. Mal'shukov, K. A. Chao
Based on the Keldysh formalism, the Boltzmann kinetic equation and the drift diffusion equation have been derived for studying spin polarization flow and spin accumulation under ef…
