Probing individual phonon-polaritonic nanoparticle-on-mirror cavities by infrared nanospectroscopy
Isabel Pascual Robledo, Iker Herrero León, Karol Kołataj +4
Nanoparticle-on-mirror (NPoM) cavities enable extreme light confinement and strong light-matter interactions, but their realization with phonon-polariton materials in the mid-infra…
Real-Space Plasmon Imaging Reveals Modified Electronic Structure of Gold at the Monolayer Limit
Andrei Bylinkin, Philippe Roelli, Naveen Shetty +8
Atomically thin materials exhibit electronic and optical properties distinct from their three-dimensional counterparts. For metals, particularly gold, monolayer studies remain larg…
Nanoscale resolved mapping of the dipole emission of hBN color centers with a scattering-type scanning near-field optical microscope
Iris Niehues, Daniel Wigger, Korbinian Kaltenecker +11
Color centers in hexagonal boron nitride (hBN) are promising candidates as quantum light sources for future technologies. In this work, we utilize a scattering-type near-field opti…
In-operando control of sum-frequency generation in tip-enhanced nanocavities
Philippe Roelli, Isabel Pascual, Iris Niehues +2
Sum-frequency generation (SFG) is a second-order nonlinear process widely used for characterizing surfaces and interfaces with monolayer sensitivity. Recently, optical field enhanc…
