Plasmons of Gold Features on Silicon Nitride Sample

 

   
   

 

AFM/NSOM Imaging of Surface Plasmons on Gold Features of Silicon Nitride Substrate

A: Top view optical image of gold/silicon-nitride sample with free laser beam illumination from bottom. AFM/NSOM with transparent optical axis is shown at top left.

B: NSOM image obtained in collection mode shows surface plasmons distribution at gold area edge.

C: AFM/NSOM collage image shows optical and topographical overlapped data of section shown on B.

D: Plasmon distribution of two slits located on above sample.

Because of their free optical axis from above and below, as well as their tip-scanning capabilities, MultiView heads MV2000, MV4000 and CV2000 are the optimal systems for this application.
