Ultra-resolution hyperspectral imaging of strained single-walled carbon nanotubes
6 nm super-resolution optical transmission and scattering spectroscopic imaging of carbon nanotubes using a nanometer-scale white light source
We demonstrated sub-5 nm spatial resolution in both visible and near-infrared wavelengths (415 to 980 nm) for the hyperspectralimaging of strained single-walled carbon nanotubes (swnt) and reconstructed true-color images to reveal the longitudinal and transverse opticaltransition-induced light absorption and scattering in the swnts.
The new technique provides rich near-field spectroscopic information that had made it possible to analyze the spatial modulation of band-structure along a single swnt induced through strain engineering.
