Applications

GRAPHENE CVD ON COPPER

RIMA™ is used to thoroughly evaluate the structural properties of graphene grown in different condition. The intrinsic specificity of Raman scattering combined with global imaging capabilities allows users to assess large of defects, number of layers and stacking order.

RAMAN MULTIPLEXING

Because of its high throughput, RIMA™ allows the acquisition of spectrally resolved maps of large area samples, without damaging the surface.

SWNT BREATHING MODES

Two narrowband tunable filters for resonance Raman spectroscopy (RRS) were designed to study the radial breathing modes of carbon nanotubes.

MONO- AND BILAYER GRAPHENE

Investigation of CVD monolayer graphene with bilayer island is performed with RIMA. Large area maps of defects, number of layers and stacking order is used to rigorously study the  growth conditions.

Si/Ti WAFER MAPS

RIMA™ was tested with a Si substrate where a pattern of Ti has been deposited. We clearly observe the main Raman mode from the Si substrate whereas no signal is coming from the Ti pattern.

CNT IN YEAST

Global Raman imaging is an exceptional technique for the analysis of large surfaces of thin films and advanced materials. Its rapidity makes it a great tool not only for universities and research institutes, but also for industrial laboratories.

VIDEO

Photon etc’s Global Imaging Technology

The Photon etc video shows the conceptual difference between hyperspectral global imaging and raster scan (line-scan, push-broom). With global imaging, the gain in acquiring 3D data, 2D spatial and 1D spectral, is important since the only a few monochromatic images are required to cover the complete  spectral range where one  needs to take the full spectrum for each point or  line in the image with other technologies.

RAMAN SHIFT CALCULATOR

Raman spectroscopy is a form of vibrational spectroscopy technique where vibrational, rotational frequencies and low-frequency modes of a system caused by the inelastic scattering of light (the Raman shift) are monitored. These vibrational frequencies are used as chemical fingerprints for the identification of molecules. Usually, Raman shifts are typically in wavenumbers, which have units of inverse length (cm-1). In order to convert between spectral wavelength, wavenumbers and frequency of shift in the Raman spectrum, we have developed this applet to compute Raman shifts and bandwidths.
