TL;DR: The observation of a fine structure in ion tracks in amorphous SiO2 using small angle x-ray scattering measurements is reported, consistent with a frozen-in pressure wave originating from the center of the ion track as a result of a thermal spike.

TL;DR: In this article, a method to numerically calculate the exact (non-circular) meniscus profile from the Kelvin equation, and compare the results of the obtained capillary force with different previous approximations and experiments is presented.

TL;DR: It is shown that the energy transferred to the electron system of SiC by energetic ions via inelastic ionization can effectively anneal pre-existing defects and restore the structural order.

TL;DR: In this article, the authors used ab initio calculations and a pure silicon tip to study the tip-surface interaction with four characteristic insulating surfaces: (i) the narrow gap TiO2 (110), (ii) the classic oxide MgO (001) surface, (iii) the ionic solid CaCO3 (10(1) over bar4) surface with molecular anion, and (iv) the wide gap CaF2 (111) surface.

TL;DR: This work identifies a major gap in understanding on the role of defects in electronic energy dissipation and electron-phonon coupling and provides insights for creating novel interfaces and nanostructures to functionalize thin film structures, including tunable electronic, ionic, magnetic and optical properties.
