Abstract

A method for preparing a transmission electron microscopy (TEM) sample for electron holography includes forming a sacrificial material over an area of interest on the sample, and polishing the sample to a desired thickness, wherein the area of interest is protected from rounding during the polishing. The sacrificial material is removed from the sample following the polishing.
