Theory for TERS of 2D 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…
Fully quantum perturbative description of correlated Stokes--anti-Stokes scattering
Raul Corrêa, Marcelo F. Santos, Carlos H. Monken +1
The process in which Raman scattering produces correlated Stokes and anti-Stokes radiation is known as Stokes--anti-Stokes (SaS) scattering. It has been shown recently that this pr…
Emergent broadband polarization entanglement from electronic and phononic Stokes-anti-Stokes indistinguishability
Diego Sier, Lucas Valente, Tiago A. Freitas +4
Recently [PRA 108, L051501 (2023)], it was shown that in a centrosymmetric cubic system, two photons from a broadband intense laser field can be converted into a pair of Stokes and…
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…
