Достоверность выявления пронизывающих дислокаций в эпитаксиальных пленках с помощью структурно-чувствительного травления

AbstractCorrespondence between threading dislocations (TDs) in epitaxial films and the etch pits observed upon selective chemical etching of the samples was studied in Ge/Si(001) heterostructures. It is established that the density of TDs revealed in epitaxial films with thicknesses h ≤ 1 μm can be significantly understated because of insufficient resolution of optical microscopy. Recommendations are given that increase the reliability of PD density estimation by means of structure-sensitive etching.

A silver-based nanoporous material was produced by dealloying (selective chemical etching) of an Ag38.75Cu38.75Si22.5 crystalline alloy. Composed of connected ligaments, this material was imaged using a scanning electron microscope (SEM) and focused ion-beam (FIB) scanning electron microscope tomography. Its mechanical behavior was evaluated using nanoindentation and found to be heterogeneous, with density variation over a length scale of a few tens of nanometers, similar to the indent size. This technique proved relevant to the investigation of a material’s mechanical strength, as well as to how its behavior related to the material’s microstructure. The hardness is recorded as a function of the indent depth and a phenomenological description based on strain gradient and densification kinetic was proposed to describe the resultant depth dependence.
