hsl 2007 – Structure of imperfect materials – <strong>Epitaxy</strong> <strong>and</strong> <strong>interface</strong> <strong>defects</strong><br />
Pseudomorphic growth<br />
Energetic considerations:<br />
γ e + γ i + E f h ≤ γ s<br />
Further growth:<br />
a) Elastic relaxation<br />
b) Plastic relaxation<br />
(E f h increases)<br />
> γ s<br />
