You are invited to register for our free webinar "Raman and PL at the Nanoscale: Why it really matters for 2D Materials" on Tuesday, June 15 at 2 PM EDT.
It’s common knowledge that Raman spectroscopy is a very important technique for characterization of 2D materials, such as graphene, TMDCs, MXenes, etc. Hyperspectral microscopic Raman imaging can further help in identification of heterogeneities in 2D materials and their heterostructures.
Quite often the scale of structural, electronic or morphological heterogeneity in these materials is on the order of few tens of nanometers or less, which is beyond the spatial resolution of conventional Raman microscopy. Tip enhanced Raman scattering (TERS) and tip enhanced photoluminescence (TEPL) can address the problem of spatial resolution.
In this webinar we’ll demonstrate how TERS and TEPL imaging can probe a number of nanoscale heterogeneities in 2D crystals: Growth related, including lateral and vertical heterostructures; substrate induced; and the morphological heterogeneities that appear (intentionally or not) in the process of exfoliation/ 2D crystal transfer. Finally, we’ll discuss hot, recent results on TERS imaging of reconstructed Moire patterns in twisted bilayers of graphene and the exciting demonstration of the ultra-low frequency TERS which opens the gates to a wonderland of nanophononics.
