Electrically-driven vibronic spectroscopy with sub-molecular resolution
Benjamin Doppagne, Michael C. Chong, Etienne Lorchat +6
A scanning tunneling microscope is used to generate the electroluminescence of phthalocyanine molecules deposited on NaCl/Ag(111). Photon spectra reveal an intense emission line at…
Monitoring Electrostatically-Induced Deflection, Strain and Doping in Suspended Graphene using Raman Spectroscopy
Dominik Metten, Guillaume Froehlicher, Stéphane Berciaud
Electrostatic gating offers elegant ways to simultaneously strain and dope atomically thin membranes. Here, we report on a detailed \textit{in situ} Raman scattering study on graph…
Direct versus indirect band gap emission and exciton-exciton annihilation in atomically thin molybdenum ditelluride (MoTe)
Guillaume Froehlicher, Etienne Lorchat, Stéphane Berciaud
We probe the room temperature photoluminescence of -layer molybdenum ditelluride (MoTe) in the continuous wave (cw) regime. The photoluminescence quantum yield of monolayer…
