hBN phonon-polaritons


Nano imaging of surface phonon polaritons (SPhP) on hexagonal boron nitride (hBN). (a) AFM height image showing homogeneous hBN surface with different layers on Si substrate; (b) s-SNOM amplitude showing strong interference fringes due to propagating SPhP along the surface on hBN; (c) s-SNOM phase showing a difference phase with alternating layer thicknesses. Images (b) and (c) show the changing wavelengths of the SPhP across the layers.

2D metamaterials

Combine S-SNOM and AFM-IR  to create remarkable new data
chirality 3D image
Complementary AFM-IR and Scattering SNOM images reveal, for the first time, the microscale origins of optical chirality on plasmonics structures. By accessing both the radiative (s-SNOM) and non-radiative (AFM-IR) information on plasmonics structures, unique and complementary plasmonic properties can be obtained. Khanikaev et al., Nat.

nano FTIR spectroscopy

Ultrafast-broadband scattering SNOM spectroscopy probing molecular vibrational information. Laser interferogram of Polytetrafluoroethylene (PTFE) shows coherent molecular vibration in the form of free-induction decay in time domain (top). The highlighted feature in sample interferogram is due to the beating of symmetric and antisymmetric mode of C-F modes in the resulting the frequency domain (bottom left). Monolayer sensitivity of nano-FTIR is demonstrated on a monolayer pNTP (bottom right). Data courtesy of Prof. Markus Raschke, University of Colorado, Boulder, US

s-SNOM imaging of multi-layer nylon and PE sample

s-SNOM can be used to measured multi-layer polymeric films . Here absorption bands at 1640 and 1540 cm-1 were observed for nylon. Subsequent s-SNOM imaging at 1640 cm-1 showed contrast between the nylon layer and PE layer. Sample provided courtesy of DSM
