Theory for tip-enhanced Raman spectroscopy of two-dimensional materials including out-of-plane Raman response
Raul Corrêa, Luiz G. Cançado, Ado Jorio
Tip-Enhanced Raman Spectroscopy (TERS) can be used to make nanoscale spatial measurements of 2D materials, such as graphene and transition metal dichalcogenides (TMDs). The TERS th…
Anomalous Tip-Sample Distance Behavior on the Tip-Enhanced Raman Spectroscopy of Graphene in Ambient Conditions
André G. Pereira, Raul Corrêa, Bianca Carneiro +5
Tip-Enhanced Raman Spectroscopy (TERS) combines Raman spectroscopy with scanning probe microscopy to overcome the spatial resolution limitation imposed by light diffraction, offeri…
Plasmonic Bi-Cavity Nanostructure for Efficient Light Collection and Localization
Vitor Monken, Raul Correa, Hudson Miranda +5
Tip-enhanced Raman spectroscopy (TERS) typically relies on high-NA excitation to generate a strong axial field at the tip apex, which shortens the working distance and constrains s…
Nano-Raman Spectroscopy Analysis of Nanoprotuberances in MoSe2
Jane Elisa Guimarães, Rafael Nadas, Rayan Alves +8
Contaminations in the formation of two-dimensional heterostructures can hinder or generate desired properties. Recent advancements have highlighted the potential of tip-enhanced Ra…
Impact of Substrate on Tip-enhanced Raman Spectroscopy --- A Comparison of Frequency Domain Simulations and Graphene Measurements
Hudson Miranda, Cassiano Rabelo, Luiz Gustavo Cancado +7
Tip-enhanced Raman spectroscopy (TERS) has reached nanometer spatial resolution for measurements performed at ambient conditions and sub-nanometer resolution at ultra high vacuum.…
Lifetime and Polarization for Real and Virtual Correlated Stokes-anti-Stokes Raman Scattering in Diamond
Filomeno S. de Aguiar Júnior, Marcelo F. Santos, Carlos H. Monken +1
The production of correlated Stokes (S) and anti-Stokes (aS) photons (SaS process) mediated by real or virtual phonon exchange has been reported in many transparent materials. In t…
