Specimen preparation of porous Au for transmission electron microscopy using cryo ion-milling.

摘要

Porous Au specimens suitable for transmission electron microscopic investigations were prepared by the Ar ion-milling equipped with a cryo-system. The cryo technique enabled the preparation of an artifact-free specimen, avoiding the deposition of Au particles induced by ion-milling. This result demonstrates that cooling is necessary for defect-free preparation of the specimens.
