Scanning transmission ion microscope with a field ion source.

چکیده
Experiments with a low-resolution scanning transmission ion microscope, using hydrogen ions from a field ionization source, indicate that it will be feasible by this approach to aim at high-resolution ion microscopy. Micrographs of unstained biological specimens have been obtained by critical range absorption of a 55 keV hydrogen ion beam at a resolution of 2000 A.

متن کاملFocused ion beam preparation of atom probe specimens containing a single crystallographically well-defined grain boundary.
Needle-shaped atom probe specimens containing a single grain boundary were produced using the focused ion beam (FIB) of a two-beam FIB/SEM (scanning electron microscope) system. The presented specimen preparation approach allows the unprecedented study of a grain boundary which is well characterised in its crystallographic orientation by means of the field ion microscope (FIM) and the tomograph...
متن کاملRapid and precise scanning helium ion microscope milling of solid-state nanopores for biomolecule detection.
We report the formation of solid-state nanopores using a scanning helium ion microscope. The fabrication process offers the advantage of high sample throughput along with fine control over nanopore dimensions, producing single pores with diameters below 4 nm. Electronic noise associated with ion transport through the resultant pores is found to be comparable with levels measured on devices made...
متن کاملBinder-free copper hexacyanoferrate electrode prepared by pulse galvanostatic electrochemical deposition for aqueous-based Al-ion batteries
Copper hexacyanoferrate (CuHCF) nanoparticles with tunnel-like Prussian blue structure were deposited on graphite substrate via pulse galvanostatic electrochemical deposition at 25 mA cm-2 with both on-time and off-time periods of 0.1 s, which presented the ability to intercalation/de-intercalation of Al ions reversibly in aqueous solution. The crystal structure of the as-prepared CuHCF f...
متن کاملRoom-temperature growth of ion-induced carbon nanofibers: Effects of ion species
Graphite surfaces were bombarded with Ne, Ar and Xe ions at 450 eV–1 keV to induce the carbon nanofiber (CNF) growth at room temperature, and the dependence of size and numerical density of ion-induced CNFs on the ion species and ion energy was investigated in detail. The ion-sputtered surfaces were covered with densely distributed conical protrusions and aligned CNFs grew on the tips, except f...
