Monolayers of MoS on Ag(111) as decoupling layers for organic molecules: resolution of electronic and vibronic states of TCNQ
Asieh Yousofnejad, Gaël Reecht, Nils Krane +2
The electronic structure of molecules on metal surfaces is largely determined by hybridization and screening by the substrate electrons. As a result, the energy levels are signific…
Vibrational excitation mechanism in tunneling spectroscopy beyond the Franck-Condon model
Gaël Reecht, Nils Krane, Christian Lotze +3
Vibronic spectra of molecules are typically described within the Franck-Condon model. Here, we show that highly resolved vibronic spectra of large organic molecules on a single lay…
Mapping the perturbation potential of metallic and dipolar tips in tunneling spectroscopy on MoS
Nils Krane, Christian Lotze, Nils Bogdanoff +4
Scanning tunneling spectroscopy requires the application of a potential difference between the sample and a tip. In metal-vacuum-metal junctions, one can safely assume that the pot…
-Radical Formation by Pyrrolic H Abstraction of Phthalocyanine Molecules on Molybdenum Disulfide
Gael Reecht, Nils Krane, Christian Lotze +1
For a molecular radical to be stable, the environment needs to be inert. Furthermore, an unpaired electron is less likely to react chemically, when it is placed in an extended orbi…
Yu-Shiba-Rusinov states in the charge-density modulated superconductor NbSe2
Eva Liebhaber, Sergio Acero Gonzalez, Rojhat Baba +6
NbSe is a remarkable superconductor in which charge-density order coexists with pairing correlations at low temperatures. Here, we study the interplay of magnetic adatoms and t…
Tuning the coupling of an individual magnetic impurity to a superconductor: quantum phase transition and transport
Laëtitia Farinacci, Gelavizh Ahmadi, Gaël Reecht +6
The exchange scattering at magnetic adsorbates on superconductors gives rise to Yu-Shiba-Rusinov (YSR) bound states. Depending on the strength of the exchange coupling, the magneti…
