Abstract

We introduce plasmonic heating assisted tip-enhanced Raman spectroscopy using the heat generated from the enhanced electromagnetic field at the apex of metallic tip that is transferred to the sample by conduction and radiation. The nanoscale heat generated at the apex was used to investigate the thermal dependence of Raman frequency of the G band from an isolated bundle of single walled carbon nanotube. The temperature coefficient of the frequency of the G band is found to be -0.02 cm-1/K. This technique can be used for thermal characterization of various materials in the nanoscale.
