Extracting the Transport Channel Transmissions in Scanning Tunneling Microscopy using the Superconducting Excess Current
Jacob Senkpiel, Robert Drost, Jan C. Klöckner +6
Transport through quantum coherent conductors, like atomic junctions, is described by the distribution of conduction channels. Information about the number of channels and their tr…
Gigahertz frame rate imaging of charge-injection dynamics in a molecular light source
Anna Rosławska, Pablo Merino, Christopher C. Leon +4
Light sources on the scale of single molecules can be addressed and characterized on their proper sub-nanometer scale by scanning tunneling microscopy induced luminescence (STML).…
Dynamical Coulomb Blockade as a Local Probe for Quantum Transport
Jacob Senkpiel, Jan C. Klöckner, Markus Etzkorn +9
Quantum fluctuations are imprinted with valuable information about transport processes. Experimental access to this information is possible, but challenging. We introduce the dynam…
Single Channel Josephson Effect in a High Transmission Atomic Contact
Jacob Senkpiel, Simon Dambach, Markus Etzkorn +9
The Josephson effect in scanning tunneling microscopy (STM) is an excellent tool to probe the properties of the superconducting order parameter on a local scale through the Ambegao…
Mapping of Yu-Shiba-Rusinov states from an extended scatterer
Markus Etzkorn, Matthias Eltschka, Berthold Jäck +2
We investigate the spatial evolution of Yu-Shiba-Rusinov (YSR) states resulting from the interaction between Copper phthalocyanine molecules and a superconducting Vanadium (100) su…
Single charge and exciton dynamics probed by molecular-scale-induced electroluminescence
Anna Rosławska, Pablo Merino, Christoph Große +5
Excitons and their constituent charge carriers play the central role in electroluminescence mechanisms determining the ultimate performance of organic optoelectronic devices. The i…
Robustness of Yu-Shiba-Rusinov resonances in presence of a complex superconducting order parameter
Jacob Senkpiel, Carmen Rubio-Verdú, Markus Etzkorn +8
Robust quantum systems rely on having a protective environment with minimized relaxation channels. Superconducting gaps play an important role in the design of such environments. T…
Signatures of phase-coherent transport and the role of quantum fluctuations in the dynamical Coulomb blockade regime
Berthold Jäck, Jacob Senkpiel, Markus Etzkorn +3
Josephson junctions operated in the dynamical Coulomb blockade regime recently gained an significant amount of attention as central building block in concepts to demonstrate the no…
Quantum Brownian motion at strong dissipation probed by superconducting tunnel junctions
Berthold Jäck, Jacob Senkpiel, Markus Etzkorn +3
We have studied the temporal evolution of a quantum system subjected to strong dissipation at ultra-low temperatures where the system-bath interaction represents the leading energy…
Critical Josephson current in the dynamical Coulomb blockade regime
Berthold Jäck, Matthias Eltschka, Maximilian Assig +3
Superconductivity is commonly described as a macroscopic quantum phenomenon. However, it arises from microscopic mechanisms occurring at the nanometer scale as illustrated, for exa…
The energy resolution function of a tunnel junction
Christian R. Ast, Berthold Jäck, Jacob Senkpiel +4
The tunnel junction between tip and sample in a scanning tunneling microscope is an ideal platform to access the local density of states in the sample through the differential cond…
Large Bandgap Opening Between Graphene Dirac Cones Induced by Na Adsorption onto an Ir Superlattice
Marco Papagno, Stefano Rusponi, Polina Makarovna Sheverdyaeva +6
We investigate the effects of Na adsorption on the electronic structure of bare and Ir cluster superlattice covered epitaxial graphene on Ir(111) using angle-resolved photoemission…
Positive and Perpendicular Exchange Bias CoO/Co Bilayers
F. Radu, M. Etzkorn, R. Siebrecht +3
We have carried out detailed experimental studies of the exchange bias effect of a series of CoO/Co(111) textured bilayers with different Co layer thickness, using the magneto-opti…
