WebAbstract Into situ TEM nanopillar contraction experiments are widely used to study the mechanical behavior of nanoscale materials. Often, the pillars are fabricated using gallium-focused ion beam (FIB) milled free a bulk sample. During the FIBBING treat, the choice of the pillar shape and the electricity of the Ga ions canned significantly impact the … WebBefore the ion-beam bombardment the thickness of the nanowires was about 100 nm (see e.g. Figure 1), and later after the irradiation the thickness reduced significantly (< 10 nm).Based on SRIM simulations[19], the projected He+ ion range for 30 keV ions in GaAs is much larger than the thickness of the nanowire. Therefore, most of the impinging ions (> …
