Name:	TERS
SPM principle:	Confocal Microscopy techniques
Size:	2x2 um

Raman microscopy with ultra-high spatial resolution. a - tip enhanced Raman scattering experiment, b - intensity of carbon nanotube G-band increases by several orders of magnitude when the probe tip is landed, c - confocal Raman image of carbon nanotube bundle. d- tip-enhanced Raman scattering (TERS) image of the same nanotube bundle. Note, TERS provides more than 4-times better spatial resolution as compared to confocal microscopy.
