A versatile platform for graphene nanoribbon synthesis, electronic decoupling, and spin polarized measurements

The on-surface synthesis of nano-graphenes has led the charge in prototyping structures with perspectives beyond silicon-based technology. Following reports of open-shell systems in graphene-nanoribbons (GNRs), a flurry of research activity was directed at ...

Upgrade of a low-temperature scanning tunneling microscope for electron-spin resonance

Nicolas Weiss, Harald Brune, François Patthey, Donat Fabian Natterer, Tobias Bilgeri, Patrick Robert Forrester

Electron spin resonance with a scanning tunneling microscope (ESR-STM) combines the high energy resolution of spin resonance spectroscopy with the atomic scale control and spatial resolution of STM. Here we describe the upgrade of a helium-3 STM with a 2D ...

Quantum state manipulation of single atom magnets using the hyperfine interaction

Harald Brune, François Patthey, Edgar Fernandes, Donat Fabian Natterer, Patrick Robert Forrester, Dante Philippe Sblendorio

The magnetic quantum states of holmium single atom magnets on MgO(100) have proven extremely robust when exposed to high magnetic fields and temperatures up to 35 K. Here we address the stability of Ho at small magnetic fields, where the hyperfine interact ...

Spin Excitations in a 4f-3d Heterodimer on MgO

Harald Brune, François Patthey, Zeljko Sljivancanin, Donat Fabian Natterer, Fabio Donati, Aparajita Singha, Christian Wäckerlin

We report on the magnetic properties of HoCo dimers as a model system for the smallest intermetallic compound of a lanthanide and a transition metal atom. The dimers are adsorbed on ultrathin MgO(100) films grown on Ag(100). New for 4f elements, we detect ...

Antiferromagnetic MnNi tips for spin-polarized scanning probe microscopy

Harald Brune, François Patthey, Donat Fabian Natterer, Tobias Bilgeri, Patrick Robert Forrester

Spin-polarized scanning tunneling microscopy (SP-STM) measures magnetoresistance with atomic resolution. While various methods for achieving SP probes have been developed, each is limited with respect to fabrication, performance, and operating conditions. ...

Giant apparent lattice distortions in STM images of corrugated sp2-hybridised monolayers

Laurent Claude, Harald Brune, Alfredo Pasquarello, François Patthey, Stefano Rusponi, Anne Lehnert, Quentin Dubout, Markus Etzkorn, Donat Fabian Natterer

We report on the strengths and limitations of scanning tunnelling microscopy (STM) when used for characterising atomic-scale features of quasi two-dimensional materials, such as graphene and single layers of hexagonal boron nitride, which may present stron ...

Quantifying residual hydrogen adsorption in low-temperature STMs

Harald Brune, François Patthey, Donat Fabian Natterer

We report on low-temperature scanning tunneling microscopy observations demonstrating that individual Ti atoms on hexagonal boron nitride dissociate and adsorb hydrogen without measurable reaction barrier. The clean and hydrogenated states of the adatoms a ...

Two Distinct Phases of Bilayer Graphene Films on Ru(0001)

Harald Brune, Marco Grioni, Stefano Rusponi, Anne Lehnert, Daniela Pacilè, Quentin Dubout, Emmanouil Frantzeskakis, Donat Fabian Natterer

By combining angle-resolved photoemission spectroscopy and scanning tunneling microscopy we reveal the structural and electronic properties of multilayer graphene on Ru(0001). We prove that large ethylene exposure allows the synthesis of two distinct phase ...

Optimizing long-range order, band gap, and group velocities for graphene on close-packed metal surfaces

Harald Brune, Stefano Rusponi, Donat Fabian Natterer

We compare different growth methods with the aim of optimizing the long-range order of a graphene layer grown on Ru(0001). Combining chemical vapor deposition with carbon loading and segregation of the surface layer leads to autocorrelation lengths of 240 ...

Ring State for Single Transition Metal Atoms on Boron Nitride on Rh(111)

Harald Brune, François Patthey, Donat Fabian Natterer

The low-temperature adsorption of isolated transition metal adatoms (Mn, Co, and Fe) onto hexagonal boron nitride monolayers on Rh(111) creates a bistable adsorption complex. The first state considerably weakens the hexagonal boron nitride- (h-BN-) substra ...
