Time-of-flight photon spectroscopy for scanning tunneling microscopy luminescence
Lebin Yu, JiÅà 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 à ngstrom-scale Tip-Enhanced Raman Imaging
Rodrigo Cezar de Campos Ferreira, Borja Cirera, JiÅà 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, JiÅà 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…
