Graphene nonoribbons for NO2 sensing

Abstract

<p>Nanomaterials provide novel possibilities for sensor applications. Here we investigate nanoelectrochemical sensing of N02 using graphene nanoribbons. Electronic properties of N02 doped nanoribbons are investigated using an ab initio calculations with accurate optimization of the sensor structures. The adsorption of N02 on graphene nanoribbon changes its conduction properties. Therefore, we compare the conduction charateristics of pristine and N02-doped nanoribbons, and investigate the details of N02 sensing based on conduction change.</p><p>This presentation occurred at the Wright State University Campus-Wide Celebration of Research, Scholarship and Creative Activities on April 8, 2011</p>
