TL;DR: The use of energetic Ne ions in engineering graphene nanostructures is discussed and their mechanical, electromechanical and chemical properties are explored using scanning probe microscopy (SPM) and SPM-based techniques.

TL;DR: A graphical bootstrapping method to quantitatively visualize large-scale high-dimensional datasets and demonstrate its successes for high-veracity mechanical mapping on a mixed polymer thin film and resolving irregular hydration structure of calcite at atomic resolution is developed.

TL;DR: The ab initio modeling reveals that oxygen adatoms possess frustrated local spin moments with possible spin-glass behavior of the surface covered by adsorbed oxygen, and indicates presence of a pseudo gap on the topmost SrO layer on pristine SrO-terminated surface, suggesting possibility for realization of a surface half-metallic film.

TL;DR: Evaluating the gating performance of amorphous indium gallium zinc oxide (a-IGZO) transistor coupled with a series of imidazolium-based ILs reveals that the EDL with different ion structures could produce inhomogeneous electric fields at the solid-electrolyte interface, and the heterogeneity of electric field-induced charge distributions at semiconductor surface could reduce the electrical conductance of a-IGO during gating process.

TL;DR: It is shown that the local potential at a nanotube on a substrate due to a probe can be calculated quantitatively, allowing experimental data to be analyzed in terms of the electronic structure of defects.
