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…
Moiré structure of MoS on Au(111): Local structural and electronic properties
Nils Krane, Christian Lotze, Katharina J. Franke
Monolayer islands of molybdenum disulfide (MoS) on Au(111) form a characteristic moiré structure, leading to locally different stacking sequences at the S-Mo-S-Au interface. Us…
