Convenient Preparation of High-Quality Specimens for Annealing Experiments in the Transmission Electron Microscope

Abstract

AbstractA procedure based on focused ion beam milling and in situ lift-out is introduced for the preparation of high-quality specimens for in situ annealing experiments in the transmission electron microscope. The procedure allows an electron-transparent lamella to be cleaned directly on a heating chip using a low ion energy and back-side milling in order to minimize redeposition and damage. The approach is illustrated through the preparation of an Al–Mn–Fe complex metallic alloy specimen.
