Laser ablation in liquids of germanium in externally applied electric fields
Abstract
Ultraviolet light from a XeF excimer laser was used to ablate a germanium target which was immersed in either distilled water or ethanol. Two electrodes in the processing container were used to produce an electric field with the strength ranging from 0 to 9.5 V/cm. The effect of externally applied electric fields on the fabricated nanoparticles was studied. The size and morphology of the obtained products were investigated using transmission electron microscopy. In each liquid, spherical nanoparticles were fabricated. It was observed that the electric field affects their size distribution. With increased electric field strength, the fabricated particles were smaller. However, in the same electric field, particles obtained in water were larger than those in ethanol, except for the 9.5 V/cm field. Additionally, spindle-shaped ablation products have been observed for ablation in ethanol under an electric field of 9.5 V/cm, while ablation in water in all studied fields resulted in filamentary webs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
