Direct observation of NiSi lateral growth at the epitaxial θ-Ni<inf>2</inf>Si/Si(1 0 0) interface

cited By 4International audienceThe first stages of NiSi phase formation at the expense of θ-Ni2Si and a Si substrate are investigated by transmission electron microscopy (TEM). These measurements show the presence of a low density of NiSi particles at the θ-Ni2Si/Si(1 0 0) interface and allow their complete shape to be determined. This stage corresponds to the lateral growth of NiSi at the epitaxial θ-Ni2Si/Si(1 0 0) interface. The shape of these particles is in agreement with the predicted models, and the shapes were fitted by an analytical expression derived from the model developed by Klinger et al. © 2015 Acta Materialia Inc.
