http://spectrumthinfilms.com/stf/ion-beam-sputtering/ WebIon-beam-thinning is a well-established sample preparation technique for transmission electron microscopy (TEM), but tedious procedures and labor consuming pre-thinning could seriously reduce its efficiency. In this work, we present a simple pre-thinning technique by using magnetorheological (MR) polishing to replace manual lapping and dimpling, and …
Webgrouped by the beam energy: The thickness of the system seems to have no systematic effect on the results. On average, the 30 keV beam produces a Y of 7.1 ±0.2 atoms/ion, whereas the 1 keV beam gives 0.98 ± 0.05 atoms/ion, as averaged over all system sizes and potentials. To better understand Webtomography of Escherichia coli cells, that a focused ion beam (FIB) can be used to thin whole frozen-hydrated cells in a convenient and essentially artifact-free way. Cryo …
WebSome effects on the properties of electron-beam evaporated thin films produced by ion bombardment of the growing film are reported. Substantial increases in the packing densities of SiO2, TiO2, and ZrO2 films have been produced as measured by the reduction in the adsorption of moisture when the films are exposed to a humid atmosphere. In a … WebA study of the factors that affect thinning rates and damage processes during the ion‐beam thinning of ceramics has been undertaken. The results of these studies are reported and related to the conditions necessary for the preparation of uniform damage free specimens. Particular emphasis is placed on the variations in specimen stoichiometry that can occur …
WebIon beam thinning for TEM samples. Ion beam thinning (ion milling) enables to thin specimens down to electron transparency. It usually is the final step after conventional grinding and in some cases after Tripod polishing. Using electric discharge, Ar+ ions of some kV are generated and focused on the sample. The goal is the crystal lattice ...
Web20 jul. 2004 · yield, as the ion beam passes over the height steps, can cause thickness striations across the lamella (the ‘‘curtain effect’’) (Szot et al., 1992; Ishitani and Yaguchi, 1996). 4. The final thinning of a lamella is performed by scan-ning the ion beam in lines and moving it inwards in fixed steps (normally half a beam diameter).
