| Popis: |
In SERS and TERS charge transfer can lead to the chemical signal enhancement. STM assisted TERS allows for applying DC electric fields between tip and sample comparably high to the fields experienced by molecules in regular devices. The influence of DC electric fields on tip enhanced Raman spectra has been reported by various authors who discussed different aspects such as reorientation of molecules, intensity changes and energy level shifts. Here we report on our progress towards a better understanding of a scanning DC electric field on tip enhanced Raman spectra of small molecules directly bound to the metallic substrate. |
