Beyond Equilibrium Raman Thermometry: Fermi-Level Control of the Anti-Stokes Response in Graphene
Martin Jindra, Luka Pirker, Tim Verhagen +7
Non-equilibrium electron and phonon populations govern heat generation and dissipation in nanoscale devices, yet their direct characterization remains challenging. Anti-Stokes Rama…
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…
