Catalyzed Adsorption at Carbon Nanotube Defects: Studies using Multireference Coupled Cluster Methods


EMSL Project ID
47720

Abstract

In this project we apply the recently developed multireference coupled cluster capabilities in NWChem to the study of physical and chemical processes in the adsorption of gas molecules to carbon nanotubes. These processes have experimentally been shown to affect the conductance of the nanotubes raising the prospect that they could be used as gas sensors. However, controversy reigns over how the gas molecules interact with the nanotubes. It has been suggested that defects play an essential role. The multireference coupled cluster method allows highly accurate studies o these interactions.
