Individual Assembly of Radical Molecules on Superconductors

High-precision molecular manipulation techniques are used to control the assembly of radical molecules (S=1/2) on a superconductor. Here we present a low-temperature STM and STS study of molecules hosting single electrons on superconducting Pb(111).

Spin Excitations of High-Spin Iron(II) in Metal-Organic Chains on Metal and Superconductor

We use on-surface coordination chemistry to synthesize on Ag(111) and superconducting Pb(111) iron-based spin chains that reveal low-energy spin excitations.

Hexadecanuclear isobutyrate nanoclusters with a {CoII14CoIII2} core

A new hexadecanuclear nanocluster with a mixed-valence {Co16} core has been prepared and fully characterized. Predominantly intracluster ferromagnetic exchange interactions were measured.

Self-Assembly of N-Rich Triimidazoles on Ag(111)

Hydrogen-bonded assemblies of N-doped heterocyclic triimidazole molecules on a Ag(111) substrate were investigated using scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED) techniques. The LEED data are consistent with simulations based on a distinct overlayer on the Ag(111) lattice. Density functional theory (DFT) calculations support the experimental results.

On-Surface Synthesis of Nitrogen-Doped Kagome Graphene

We report the on-surface reaction on Ag(111) for the synthesis of two-dimensional N-doped graphene sheets possessing a honeycomb Kagome lattice. STM, AFM and DFT methods are applied to scrutinize the structural and electronic properties. We demonstrate the semiconducting character of the lattice and the emergence of Kagome flat bands near the Fermi level.

Bottom-up Synthesis of Nitrogen-doped Porous Graphene Nanoribbons

Nitrogen-doped porous graphene nanoribbons (N-GNRs) were synthesized on Ag(111). A combination of scanning tunneling microscopy, atomic force microscopy, scanning tunneling spectroscopy and density functional theory has been applied for the characterization of the nanoribbon.

On-surface Synthesis and Characterization of Triply-fused Porphyrin-graphene Nanoribbon Hybrids

The covalent fusion of a graphene nanoribbon with porphyrins through on-surface synthetic protocol is reported. The atomically precise structure has been characterized by STM and nc-AFM. The electronic properties have been investigated by STS in combination with DFT calculations, which reveals a low electronic gap of 0.4 eV.
