An array of dislocations in a strained epitaxial layer. I. Elastic energy
TL;DR: In this article, the authors formulated the self energy of an array of dislocations in a strained epitaxial layer as the sum of self energy and the interaction energy, which represents the formation energy of the disllocations.

Effect of elastic constants on the critical thickness of an epilayer
Abstract: Elastic constants of an epilayer usually differ from that of its substrate. The effect of this difference on the critical thickness of an epilayer is investigated via isotropic elasticity. The results indicate that the self-energy of a mismatch dislocation is controlled by the soft phase between the epilayer and the substrate, while the interaction energy depends only on the elastic constants of the thin film. It is easier for a dislocation to be formed if the substrate is softer than the film, and consequently the critical thickness is smaller. On the other hand, a soft epilayer can be very thick without any mismatch dislocation.

In situ formation of Cu–Sn–Ni intermetallic nanolayer as a diffusion barrier in preplated lead frames
TL;DR: In this paper, a technique for impeding Cu outdiffusion in preplated lead frames was developed by electroplating a 3-4nm thick epitaxy-like and dense (Cu,Ni)3Sn intermetallic-compound (IMC) layer.
