Abstract: S1.00102 : Gas molecule adsorption on silicene nanoribbons: Conductance modulation and contact effects
Author:
We investigate the effects of adsorption of gas molecules on the
quantum conduction of silicene nanoribbons with and without
silver contacts, using ab initio methods and Green's function
formalism. The adsorption positions and orientations are
determined through energy calculations and structure
optimizations for NO$_2$,CO$_2$, and CO gas molecules. The
conduction change upon gas molecules adsorption is studied for
isolated silicene nanoribbons and for silicene nanoribbons on
silver side contacts for potential applications as ultrasensitive
nanoelectrochemical sensors.
