Evidence of graphene-like electronic signature in silicene nanoribbons

We report on the electronic properties of straight, 1.6 nm wide, silicene nanoribbons on Ag(110), arranged in a one-dimensional grating with a pitch of 2 nm, whose high-resolution scanning tunneling microscopy images reveal a honeycomb geometry.

Angle-resolved photoemission shows quantum confined electronic 

states of one-dimensional character. The silicon banddispersion along the direction of the nanoribbons suggests a behavior analogous to the Dirac cones of graphene on different substrates.
