چکیده
|
We demonstrate the chemical sensing capability of silver nanostructured films grown by cryogenic oblique angle deposition (oad). for comparison,the films are grown side by side at cryogenic (100 k) and at room temperature (300 k) by e-beam evaporation. based on the observed structural differences,it was hypothesized that the cryogenic oad silver films should show an increased surface enhanced raman scattering (sers) sensitivity. comsol simulation results are presented to validate this hypothesis. experimental sers results of 4-aminobenzenethiol (4-abt) raman test probe molecules in vapor phase show good agreement with the simulation and indicate promising sers applications for these nanostructured thin films. © 2013 piyush shah et al.
