Near-field Raman spectroscopy of nanocarbon materials.

Nanocarbon materials, including sp(2) hybridized two-dimensional graphene and one-dimensional carbon nanotubes, and sp(1) hybridized one-dimensional carbyne, are being considered for the next generation of integrated optoelectronic devices. The strong electron-phonon coupling present in these nanocarbon materials makes Raman spectroscopy an ideal tool to study and characterize the material and device properties. Near-field Raman spectroscopy combines non-destructive chemical, electrical, and structural specificity with nanoscale spatial resolution, making it an ideal tool for studying nanocarbon systems. Here we use near-field Raman spectroscopy to study strain, defects, and doping in different nanocarbon systems.
