This is in contrast to conventional molecular excitation thresholds, which are independent of the current direction and therefore always occur at both positive and negative bias. This polarity selectivity is found to coincide with the spatial distribution of occupied and empty orbitals. Because of the interaction with the substrate, charge transfer into the doubly degenerate dπ orbitals of MnPc takes place. The resulting Jahn-Teller effect lifts the degeneracy and leads to an isospin- or pseudospin-flip excitation, the inelastic analogue of an orbital Kondo resonance. info:eu-repo/grantAgreement/ES/MINECO/MAT2015-66888-C3-2R info:eu-repo/grantAgreement/ES/MINECO/MAT2016-78293-C6-6R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 9.227 2018 PHYSICS, MULTIDISCIPLINARY 6 / 81 = 0.074 2018 Q1 T1 3.571 2018 Physics and Astronomy (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hsu, Pin-Jui Böhme, Markus Schneider, Katrhin Senkpiel, Jacob (orcid)0000-0002-3260-9641 Serrate, David Universidad de Zaragoza Bode, Matthias Lorente, Nicolás 2003 395 Universidad de Zaragoza Dpto.
