Phonon softening and slowing down of charge-density-wave fluctuations in BaNiAs
Yu Song, Shan Wu, Xiang Chen +7
BaNiAs is a nonmagnetic analogue of the iron pnictide superconductors, and in its tetragonal state exhibits an incommensurate charge-density-wave (IC-CDW) and a sizable ela…
Magnetic Field-Free Giant Magnetoresistance in a Proximity- and Gate-Induced Graphene Spin Valve
Yu Song
Due to its two dimensional nature, ferromagnetism and charge doping can be induced by proximity and electric field effects in graphene. Taking advantage of these features, we propo…
Spin-Valley Beam Splitter in Graphene
Yu Song, Lei Xie, Zhi-Gui Shi +2
The fourfold spin-valley degenerate degrees of freedom in bulk graphene can support rich physics and novel applications associated with multicomponent quantum Hall effects and line…
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…
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,…
