Fano Resonance in the Nonadiabatically Pumped Shot Noise of a Time-Dependent Quantum Well in 2DEG and Graphene
Rui Zhu, Jiao-Hua Dai, Yong Guo
Interference between different quantum paths can generate Fano resonance. One of the examples is transport through a quasibound state driven by time-dependent scattering potential.…
Coulomb Interaction Effects on the Terahertz Photon-Assisted Tunneling through a InAs Quantum Dot
R. -Y. Yuan, G. -B. Zhu, X. Zhao +4
Recently, the terahertz (THz) photon-assisted tunneling (PAT) through a two-level InAs quantum dot (QD) has been successfully realized in experiment [Phys. Rev. Lett. {\bf 109}, 07…
Generation of a fully valley-polarized current in bulk graphene
Yu Song, Feng Zhai, Yong Guo
The generation of a fully valley-polarized current (FVPC) in bulk graphene is a fundamental goal in valleytronics. To this end, we investigate valley-dependent transport through a…
Negative differential resistances with back gate-controlled lowest operation windows in graphene double barrier resonant tunneling diodes
Yu Song, Han-Chun Wu, Yong Guo
We theoretically investigate negative differential resistance (NDR) of massless and massive Dirac Fermions in double barrier resonant tunneling diodes based on sufficiently short a…
Giant Goos-Hänchen Shift in Graphene Double-barrier Structures
Yu Song, Han-Chun Wu, Yong Guo
We report giant Goos-Hänchen shifts [Goos and Hänchen, Ann. Phys. 436, 333 (1947)] for electron beams tunneling through graphene double barrier structures. We find that inside the…
Two-dimensional group delay in graphene probed by spin precession measurements
Yu Song, Han-Chun Wu, Yong Guo
We take graphene as an example to demonstrate that the present widely adopted expression is only the scattering component of a true 2D group delay in the condensed matter context,…
