Rapid development of magnetic nanotechnologies calls for experimental techniques capable of providing magnetic information with subnanometre spatial resolution. Available probes of magnetism either detect only surface properties, such as spin-polarized scanning tunnelling microscopy, magnetic force microscopy or spin-polarized low-energy electron microscopy, or they are bulk probes with limited...

Partial oxidation of methanol to formaldehyde over Cu(110) is one of the most studied catalytic reactions in surface science, yet the local site of the reaction intermediate, methoxy, remains unknown. Using a combination of experimental scanned-energy mode photoelectron diffraction, and density functional theory, a consistent structural solution is presented in which all methoxy species occupy ...

The adsorption of subphthalocyanine (SubPc) on the Au(111) surface has been studied by scanning tunnelling microscopy (STM). Depending on coverage and deposition temperature, four different phases have been observed, of which two are coexisting. Spontaneous symmetry breaking inducing mirror domains is observed for all structures. Supramolecular chirality is expressed at different levels and len...

During the past 20 years, the manipulation of atoms and molecules at surfaces has allowed the construction and characterization of model systems that could, potentially, act as building blocks for future nanoscale devices. The majority of these experiments were performed with scanning tunnelling microscopy at cryogenic temperatures. Recently, it has been shown that another scanning probe techni...

The tri-para-carboxylic polychlorotriphenylmethyl radical adsorption on a Cu/Au(111) surface has been investigated in ultra-high vacuum environment. The presence of copper favours the formation of metal-organic assemblies, which are analysed using scanning tunnelling microscopy (STM) and high resolution electron energy loss spectroscopy (HREELS). DFT methods indicate that the unpaired electron ...

Scanning tunnelling microscopy and X-ray reflectivity are used to characterize adlayers of perylenetetracarboxylic diimide (PTCDI) deposited on epitaxial graphene (EG) on SiC(0001). PTCDI adopts a herringbone structural phase on EG/SiC that can accommodate sub-5 nm voids with molecularly defined boundaries and isolated molecular vacancies at room temperature. The PTCDI monolayer remains intact ...

The interaction of a de novo synthesised ester with single crystal metal surfaces has been investigated as a model system for the heterogeneous hydrogenolysis of esters. Scanning tunnelling microscopy measurements show dissociative adsorption at room temperature on Cu(110) but no significant reaction on Au(111). The dissociative pathway has been identified by comparing with possible fragment sp...

Organic solid/solid wetting deposition (OSWD) is an easy, low cost method to prepare epitaxial monolayers of organic semiconductors under ambient conditions. This chapter describes various approaches to induce complexity into highly ordered monolayers with Scanning Tunnelling Microscopy (STM): nanomanipulated self-assembly aiming towards molecular data storage, locally guided selfassembly to ac...

This communication describes scanning tunnelling microscopy investigations of the electronic properties of singlewalled carbon nanotubes (SWNTs). First, the unique relationship between the atomic structure and electronic properties of SWNTs is presented. Second, structural defects in nanotubes are addressed, and quantum size effects in SWNTs are discussed. Lastly, the effects of magnetic impuri...
