We present the transport characteristics of individual silicene nanoribbons (SiNRs) grown on Ag(110). By lifting up a single SiNR with a low-temperature scanning tunneling microscope tip, a nanojunction consisting of tip, SiNR and Ag is fabricated. In the differential conductance spectra of the nanojunctions fabricated by this methodology, a peak appears at the Fermi level which is not observed...

We investigate the structure and physical properties of the undoped bilayer silicene through first-principles calculations and find the system is intrinsically metallic with sizable pocket Fermi surfaces. When realistic electron-electron interaction turns on, the system is identified as a chiral d+id' topological superconductor mediated by the strong spin fluctuation on the border of the antife...

The synthesis of new Xenes and their potential applications prototypes have achieved significant milestones so far. However, to date the realization Xene heterostructures in analogy with well known van der Waals remains an unresolved issue. Here, a heterostructure concept based on epitaxial combination silicene stanene Ag(111) is introduced, how one layer enables another different nature grow t...
