While Lu adatoms display the same spectra on both surfaces, tunnelling spectra of Tm on Cu2N indicate a state at ¿0.8 V or ¿1.9 V bias, depending on the 4f population of the adatom, 4f12 or 4f13, which is not present on Tm atoms adsorbed on Cu(100). Although inelastic 4f-spin-flip excitations were not detected, variation of tunnelling through the strongly correlated d-electrons indicates that the insulating layer opens a pathway to access the electronic state of those 4f electrons in the single adatom. info:eu-repo/grantAgreement/ES/DGA/E10-17D info:eu-repo/grantAgreement/ES/MICINN/MAT2015-66726-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.676 2020 PHYSICS, ATOMIC, MOLECULAR & CHEMICAL 8 / 37 = 0.216 2020 Q1 T1 CHEMISTRY, PHYSICAL 77 / 162 = 0.475 2020 Q2 T2 1.052 2020 Physics and Astronomy (miscellaneous) 2020 Q1 Physical and Theoretical Chemistry 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion De La Fuente, César Universidad de Zaragoza (orcid)0000-0001-6117-9858 Ciria, Miguel Universidad de Zaragoza (orcid)0000-0003-1930-1455 Serrate, David Universidad de Zaragoza (orcid)0000-0002-3260-9641 Loth, Sebastian Arnaudas, José Ignacio Universidad de Zaragoza (orcid)0000-0002-2624-6004 2003 395 Universidad de Zaragoza Dpto.
