Electron Wave Function in Armchair Graphene Nanoribbons

, 2010
By using analytical solution of a tight-binding model for armchair nanoribbons, it is confirmed that the solution represents the standing wave formed by intervalley scattering and that pseudospin is invariant under the scattering.

Transport characteristics of a silicene nanoribbon on Ag(110)

Beilstein Journal of Nanotechnology, 2017
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.

Raman spectroscopy on etched graphene nanoribbons

, 2011
We investigate etched single-layer graphene nanoribbons with different widths ranging from 30 to 130 nm by confocal Raman spectroscopy. We show that the D-line intensity only depends on the edge-region of the nanoribbon and that consequently the ...

Tunable mid-infrared coherent perfect absorption in a graphene meta-surface

, 2015
We exploited graphene nanoribbons based meta-surface to realize coherent perfect absorption (CPA) in the mid-infrared regime. It was shown that quasi-CPA frequencies, at which CPA can be demonstrated with proper phase modulations, exist for the graphene ...

Size effect of Ruderman-Kittel-Kasuya-Yosida interaction mediated by electrons in nanoribbons

, 2011
We calculated the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between the magnetic impurities mediated by electrons in nanoribbons. It was shown that the RKKY interaction is strongly dependent on the width of the nanoribbon and the transverse ...
