Strain-induced effects in the electronic and spin properties of a monolayer of ferromagnetic GdAg2
Alexander Correa, Bin Xu, Matthieu J. Verstraete +1
We report on the structural, electronic and magnetic properties of a monolayer of GdAg2, forming a moiré pattern on Ag(111). Combining scanning tunneling microscopy and ab-initio s…
Width-Dependent Band Gap in Armchair Graphene Nanoribbons Reveals Fermi Level Pinning on Au(111)
Néstor Merino-Díez, Aran Garcia-Lekue, Eduard Carbonell-Sanromà +7
We report on the energy level alignment evolution of valence and conduction bands of armchair-oriented graphene nanoribbons (aGNR) as their band gap shrinks with increasing width.…
Spectroscopic perspective on the interplay between electronic and magnetic properties of magnetically doped topological insulators
Jonas A. Krieger, Cui-Zu Chang, Marius-Adrian Husanu +11
We combine low energy muon spin rotation (LE-SR) and soft-X-ray angle-resolved photoemission spectroscopy (SX-ARPES) to study the magnetic and electronic properties of magnetica…
Bottom-up fabrication of atomically precise graphene nanoribbons
Martina Corso, Eduard Carbonell-Sanromà, Dimas G. de Oteyza
Graphene nanoribbons (GNRs) make up an extremely interesting class of materials. On the one hand GNRs share many of the superlative properties of graphene, while on the other hand…
Electronic Stopping of Slow Protons in Oxides: Scaling Properties
D. Roth, B. Bruckner, G. Undeutsch +10
Electronic stopping of slow protons in ZnO, VO2 (metal and semiconductor phases), HfO2, and Ta2O5 was investigated experimentally. As a comparison of the resulting stopping cross s…
Submolecular resolution by variation of IETS amplitude and its relation to AFM/STM signal
Bruno de la Torre, Martin Švec, Giuseppe Foti +8
Here we show scanning tunnelling microscopy (STM), non-contact atomic force microscopy (AFM) and inelastic electron tunnelling spectroscopy (IETS) measurements on organic molecule…
