Abstract
We report a first-principles study to investigate the switching behavior in a nitro-oligo(phenylene ethylene) molecule bridged between a silicon slab and a single wall carbon nanotube (SWCNT) mat. Our results suggest that the switching in the device may be driven by conformational changes in the molecule upon the application of an electric field. In addition, we find that the nature of the contact at the interface of the SWCNT mat plays an important role in the switching.
