Scanning tunneling microscopy using CO-terminated probes with tilted and straight geometries
Ivan Abilio, Nicolas Néel, Jörg Kröger +1
Scanning tunneling microscopy using a CO-functionalized tip is combined with simulations to explore the impact of the CO tilt angle on topographies of a single Cu atom and CO molec…
Preparation of graphene bilayers on platinum by sequential chemical vapour deposition
Johannes Halle, Alexander Mehler, Nicolas Néel +1
A cheap and flexible method is introduced that enables the epitaxial growth of bilayer graphene on Pt(111) by sequential chemical vapour deposition. Extended regions of two stacked…
Adsorption and desorption of hydrogen at nonpolar GaN(1-100) surfaces: Kinetics and impact on surface vibrational and electronic properties
L. Lymperakis, J. Neugebauer, M. Himmerlich +4
The adsorption of hydrogen at nonpolar GaN(1-100) surfaces and its impact on the electronic and vibrational properties is investigated using surface electron spectroscopy in combin…
Screening of electron-phonon coupling in graphene on Ir(111)
M. Endlich, A. Molina-Sánchez, L. Wirtz +1
The phonon dispersion of graphene on Ir(111) has been determined by means of angle-resolved inelastic electron scattering and density functional calculations. Kohn anomalies of the…
Two-Site Kondo Effect in Atomic Chains
N. Néel, R. Berndt, J. Kröger +3
Linear CoCu_nCo clusters on Cu(111) are fabricated by means of atomic manipulation. They represent a two-site Kondo system with tunable interaction. Scanning tunneling spectroscopy…
Kondo effect of a Co atom on Cu(111) in contact with an Fe tip
N. Neel, J. Kroeger, R. Berndt
Single Co atoms, which exhibit a Kondo effect on Cu(111), are contacted with Cu and Fe tips in a low-temperature scanning tunneling microscope. With Fe tips, the Kondo effect persi…
