Argon Ion Beam milling. Wet etching can often be damaging to samples, and for some materials there are no appropriate chemicals. In these cases Ion Beam milling can be used, which produces a cleaner etch profile and is more controllable and less damaging to delicate samples. The group possess a Millatron IV Argon Ion beam milling machine, a ...

High energy focused ion beam (FIB) milling produces ion-induced damage into TEM samples and a certain amount of Ga ions implantation cannot be avoided. Additional polishing of FIB lamellae at low voltages can damage the sample further. To overcome these disadvantages, a low-energy Ar +-milling of a FIB lamellae can be applied [1,2].In this work, we focus on TEM sample preparation of different ...

Ion milling of thin‐film GaN, InN, AlN, and InGaN was performed with 100–500 eV Ar + ions at beam angles of incidence ranging from 0° to 75° from normal incidence. The mill rates normalized to the Ar + beam current for the single‐crystal GaN, AlN, and InGaN were typically a factor of 2 lower than for GaAs and InP. For the polycrystalline InN, the mill rates were similar to those of ...
