Tip-Enhanced Raman Spectroscopy (TERS) for Chemical Imaging at the Nanoscale

As an alternative approach to achieve lateral resolution far below the diffraction limit Tip-Enhanced Raman Spectroscopy (TERS) can be applied. The results presented in this study demonstrate that the alpha300 SR from WITec is a TERS ready system capable of performing various tip-enhanced Raman Spectroscopy experiments. The results prove that this technique is suitable for chemical imaging at a resolution beyond the diffraction limit.
