Raman-detected quantum dot microscopy for nanoscale electrostatic potential imaging
Jiří Doležal, Amandeep Sagwal, Rodrigo Cezar de Campos Ferreira +1
Quantification of electrostatic potentials at the nanoscale is crucial for understanding the principles governing properties of materials across multiple length scales. Currently,…
Time-of-flight photon spectroscopy for scanning tunneling microscopy luminescence
Lebin Yu, Jiří Doležal, Maximilian Rödel +4
We build and commission a time-of-flight photon spectrometer (TOFS) for scanning tunneling microscopy luminescence (STML). We obtain the spectrum by exploiting the wavelength depen…
Locally-Induced Stark Shifts of Collective Excitonic Modes in Polyradical Aggregates
Amandeep Sagwal, Rodrigo Cezar de Campos Ferreira, Petr Kahan +4
Active control of dark long-lived excitonic states in molecular aggregates using local electric fields is a pivotal challenge for advancing nanoscale optoelectronics and quantum de…
Adsorption-Driven Symmetry Lowering in Single Molecules Revealed by Ångstrom-scale Tip-Enhanced Raman Imaging
Rodrigo Cezar de Campos Ferreira, Borja Cirera, Jiří Doležal +7
The vibrational landscape of adsorbed molecules is central to understanding surface interactions at the atomic scale, influencing phenomena from catalysis to molecular electronics.…
Disentangling the components of a multiconfigurational excited state in isolated chromophore
Rodrigo Cezar de Campos Ferreira, Amandeep Sagwal, Jiří Doležal +2
Studying the excited states of doublets is challenging for their typically multiconfigurational character. We employ light-scanning-tunneling microscopy (light-STM) to investigate…
Resonant TERS of a Single-Molecule Kondo System
Rodrigo Cezar de Campos Ferreira, Amandeep Sagwal, Jiří Doležal +4
Single-molecule tip-enhanced Raman spectroscopy (TERS) under ultra-high vacuum (UHV) and cryogenic conditions enables exploration of the relations between the adsorption geometry,…
Single-molecule time-resolved spectroscopy in a tunable STM nanocavity
Jiří Doležal, Amandeep Sagwal, Rodrigo Cezar de Campos Ferreira +1
The spontaneous fluorescence rates of single-molecule emitters are typically on the order of nanoseconds. However coupling them with plasmonic nanostructures can substantially incr…
