Abstract: | This paper shows that the local electric field distribution near the nanostructure
metallic surface is obtained by solving the Laplace equation, and furthermore, the
configuration of CO molecules adsorbed on a Pt nanoparticle surface is obtained by
using Monte Carlo simulation. It is found that the uneven local electric field
distribution induced by the nanostructure surface can influence the configuration of
carbon monoxide (CO) molecules by a force, which drags the adsorbates to the poles
of the nanoparticles. This result, together with our results obtained before, may
explain the experimental results that the nanostructure metallic surface can lead to
abnormal phenomena such as anti-absorption infrared effects. |
