Tunable Localized Charge Transfer Excitons in a Mixed Dimensional van der Waals Heterostructure
Mahfujur Rahaman, Emanuele Marino, Alan G. Joly +9
Observation of interlayer, charge-transfer (CT) excitons in van der Waals heterostructures (vdWHs) based on 2D-2D systems has been well investigated. While conceptually interesting…
Multimodal Tip-Enhanced Nonlinear Optical Nano-Imaging of Plasmonic Silver Nanocubes
Chih-Feng Wang, Patrick Z. El-Khoury
Optical field localization at plasmonic tip-sample nanojunctions has enabled high spatial resolution chemical analysis through tip-enhanced linear optical spectroscopies, including…
Femtosecond-Nanometer Visualization of Exciton Dynamics in MoSe
Paul M. Sass, Patrick Z. El-Khoury
Femtosecond (fs)-resolved photoemission electron micrographs of single and few-layer MoSe track exciton dynamics in this model 2D quantum material system with joint nanometer (…
A Simplified Approach to Simulating Raman Spectra from Ab Initio Molecular Dynamics
Edoardo Aprà, Ashish Bhattarai, Eric Baxter +3
We describe a simplified approach to simulating Raman spectra using ab initio molecular dynamics (AIMD) calculations. Our protocol relies on on-the-fly calculations of approximate…
Nanoscale Chemical Reaction Imaging at the Solid-Liquid Interface via TERS
Ashish Bhattarai, Patrick Z. El-Khoury
Plasmon-enhanced chemical transformations at the solid-liquid interface can be imaged with high sensitivity, chemical selectivity, and nanoscale precision through tip-enhanced Rama…
Taking the Plunge: Nanoscale Chemical Imaging of Functionalized Gold Triangles in H2O via TERS
Ashish Bhattarai, Alan G. Joly, Andrey Krayev +1
We demonstrate fast (0.25 s/pixel) nanoscale chemical imaging in aqueous solution via tip-enhanced Raman scattering (TERS), with sub-15 nm spatial resolution. The substrate consist…
