Subsurface Raman Imaging with Nanoscale Resolution.
In: Nano Letters, Vol. 6, No. 4: pp. 744-749
We report on chemically specific, subsurface imaging with high spatial resolution. Using tip-enhanced Raman spectroscopy, we probe carbon nanotubes buried beneath a host dielectric media. We demonstrate our ability to map and resolve specific vibrational modes with 30 nm spatial resolution for dielectric layers with different thicknesses.
