Valley and spin pump by scattering at non-magnetic disorders
Xing-Tao An, Jiang Xiao, M. W. -Y. Tu +3
In solid, the crystalline structure can endow electron an internal degree of freedom known as valley, which characterizes the degenerate energy minima in momentum space. The recent…
Quantum coherence of the molecular states and their corresponding currents in nanoscale Aharonov-Bohm interferometers
Jian-Heng Liu, Matisse Wei-Yuan Tu, Wei-Min Zhang
By considering a nanoscale Aharonov-Bohm (AB) interferometer containing a parrallel-coupled double dot coupled to the source and drain electrodes, we investigate the AB phase oscil…
Transient probing of the symmetry and the asymmetry of electron interference
Matisse Wei-Yuan Tu, Amnon Aharony, Ora Entin-Wohlman +2
The transient processes of electron transport in nano-scale devices exhibit special phenomena that exist only in the transient regime. Besides how fast the steady states are approa…
