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,…
