Observation of the Ferromagnetic Kondo Effect
Elia Turco, Nils Krane, Hongyan Chen +5
The quest for quantum ground states beyond the conventional Fermi-liquid paradigm remains a central challenge in many-body physics. The ferromagnetic Kondo effect represents a part…
Tunable Luminescence From a Single Free-Base Porphyrin Molecule By Controlled Access to Optically Active States
Eve Ammerman, Nils Krane, Bruno Schuler
Scanning tunneling microscopy-induced luminescence (STML) provides access to the optical properties of individual molecules through a cascade of relaxation processes between many-b…
Electronic and magnetic properties of single chalcogen vacancies in MoS/Au(111)
Sergey Trishin, Christian Lotze, Nils Krane +1
Two-dimensional (2D) transition-metal dichalcogenides (TMDC) are considered highly promising platforms for next-generation optoelectronic devices. Owing to its atomically thin stru…
Exchange interactions and intermolecular hybridization in a spin-1/2 nanographene dimer
N. Krane, E. Turco, A. Bernhardt +8
Phenalenyl is a radical nanographene with triangular shape that hosts an unpaired electron with spin S = 1/2. The open-shell nature of phenalenyl is expected to be retained in cova…
Variations of vibronic states in densely-packed structures of molecules with intramolecular dipoles
Sergey Trishin, Christian Lotze, Johanna Richter +5
Electrostatic potentials strongly affect molecular energy levels and charge states, providing the fascinating opportunity of molecular gating. Their influence on molecular vibratio…
Direct observation of the magnetic ground state of the two smallest triangular nanographenes
Elia Turco, Annika Bernhardt, Nils Krane +4
Fusion of three benzene rings in a triangular fashion gives rise to the smallest open-shell graphene fragment, the phenalenyl radical, whose -extension leads to an entire family…
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…
