Grain boundary segregation is a phenomenon studied both experimentally and theoretically for decades. The interest in this phenomenon is evoked not only by its close relationship to temper embrittlement but also by its ability to stabilize nanocrystalline structures by solute segregation in the concept of Grain Boundary Engineering.
A full description of the exact temperature and solute...

The term "devil's staircase" of phase transitions is used to refer to an infinite sequence of ordered phases in a finite volume of the phase space. This phenomenon has a great potential for production of two-dimensional nanoscale objects, because one can create an infinite number of different ordered structures with different cell periods and properties using only one type of building blocks...

In XPS, argon gas cluster ion beams (GCIB) are an exciting new tool for sputter etching and depth profiling of materials. However, little is currently known of their effectiveness in reducing preferential sputtering compared to monatomic argon bombardment for many technologically important inorganic compounds. In this work, XPS depth profiles through various metal oxide thin films using...

With the progressive development of femtosecond lasers, high-order harmonic generation (HHG) has become a standard technique to produce a widely tunable photon energy spectrum in the laboratory. However, the application of HHG-based light sources to electron spectroscopy and microscopy has been limited by the space-charge effects at kilohertz repetition rates of high power laser systems. With...

Molecular self-assembly is the most promising approach for the direct preparation of functional nanomaterials. Recently, the coordination-driven self-assembly are increasingly being used to create metal-organic structures of varying complexity on the solid surface: discrete polygons, cages, one-dimensional polymers, two-dimensional porous networks [1,2]. In comparison with other non-covalent...

Titanium dioxide is a metal oxide with many relevant technological properties for photocatalysis, chemical reactivity, electrical conductivity and solar energy harvesting. TiO2 is an inert insulator in stoichiometric form and it can be easily reduced into a n-type semiconductor TiO2-x with the transformation of Ti4+ to Ti3+ ions. This reduction is also characterized by the excess electrons...

The bottom-up fabrication strategy [1] has introduced the possibility to grow carbon nanostructures with atomic precision and hence allows to controllably tune their electronic properties. The approach building on the predefined colligation and dehydrogenation of specifically designed precursor monomers has been successfully applied for the synthesis of various types of graphene nanoribbons...

Graphene functionalization is an important step for the development of graphene-based materials with tailored electronic properties. However, its high chemical inertness makes difficult a selective covalent functionalization, and most of the works performed up to the date report electrostatic molecular adsorption or unruly functionalization. We show a new mechanism for promoting highly...

An investigation on the secondary electron emission (SEE) properties and stability of nanometric carbon coatings is reported. The key to creating an ideal material to avoid avoiding multipactor effect or electron cloud in large particle accelerators, is to modify its SEE properties to obtain SEY<1 in all primary energy range. The SEE coefficient (SEY) was measured by single-pulse electron...

Magnetite (Fe$_3$O$_4$) is attracting attention as a potential material for spintronic devices due to the predicted half-metallic behavior with a high Curie temperature of 858 K [1]. The recent trend toward high densification of devices increases the importance of the surfaces. In our previous work, non-collinear magnetic structures are revealed at the Fe/MgO(001) interface [2] and on the...

Tin (Sn) atomic layers attract considerable interest owing to their spin-dependent physical properties caused by their strong spin–orbit interaction. We have studied the spin-dependent band structure in a Sn atomic layer that is intercalated into the graphene/SiC(0001) interface [1] using laser-based spin- and angle-resolved photoemission spectroscopy (laser-SARPES) . We can not only obtain...

Porous structures in anodic coatings, such as those formed by plasma electrolytic oxidation (PEO), are potentially favourable for the addition of material that improves the surface properties. The PEO process results in relatively thick ceramic coatings, which are formed in aqueous electrolytes under high voltages that cause formation of microdischarges on the coating due to dielectric...

Due to a strong spin-orbit interaction, the surface states of Sb (111) are similar to those for topological insulators. The surface states are protected by time-reversal symmetry and have linear energy-momentum dispersion relation. Surface modification (for example, defects in surface structure) leads to a local break of the surface translational symmetry and can change surface states. It is...
