Epitaxial fabrication of AgTe monolayer on Ag(111) and the sequential growth of Te film
Haoyu Dong, Le Lei, Shuya Xing +12
Transition-metal chalcogenides (TMCs) materials have attracted increasing interest both for fundamental research and industrial applications. Among all these materials, two-dimensi…
Evidence for topological proximity effect in graphene coupled to topological insulator
Liang Zhang, Ben-Chuan Lin, Yan-Fei Wu +3
The emergence of topological order in graphene is in great demand for the realization of quantum spin Hall states. Recently, it is theoretically proposed that the spin textures of…
Gate-Tunable Tunneling Resistance in Graphene/Topological Insulator Vertical Junctions
Liang Zhang, Yuan Yan, Han-Chun Wu +2
Graphene-based vertical heterostructures, particularly stacks incorporated with other layered materials, are promising for nanoelectronics. The stacking of two model Dirac material…
Ballistic collective group delay and its Goos-Hänchen component in graphene
Yu Song, Han-Chun Wu
We theoretically investigate the experimental observable of the ballistic collective group delay (CGD) of all the particles on the Fermi surface in graphene. First, we reveal that,…
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,…
