Nanoscale FTIR Spectroscopy in 2D Materials

The wavenumber range of the nanoIR3-s Broadband is from 670 cm-1 to 4,000 cm-1 which is beyond any other system in the market, allowing us to observe spectra that have not been seen by other researchers. The system’s stability, combined with the exceptionally high-power broadband laser, leads to new horizons in nanoscale spectroscopy.
Dr. Jiong Yang, University of New South Wales

The capability of the nanoIR3-s Broadband exceeded our expectations. The signal-noise-ratio is superb. As such, we could obtain spectra as clear as spectra of a conventional FTIR at nanoscale resolutions. Excitingly, we could see new vibrational features that are generated by the boundaries that have not been reported previously.

High Resolution Imaging

The nanoIR3-s Broadband delivers high resolution nano-optical images of a wide range of optical phenomena, including graphene plamonics and surface phonon polaritons in hexagonal boron nitride (hBN), and chemical imaging of biological and organic samples.

The example below shows near-field optical images using a spatio-spectral scan. These illustrate a complete surface phonon polariton frequency response on a hBN flake across a 200 cm-1 range. Taken with 3 cm-1 spectral resolution and 10 cm-1 imaging step resolution. 1.5×1.5 µm with 10 nm pixel resolution.
