3. 2 Wetting Layer Tailored by Epitaxial Stress
Most epitaxial films wet the substrates to varying degrees in heteroepitaxy. In the paradigm systems of the QD epitaxial growth, InAs/OaAs (001) and Ge/Si(001), the critical wetting layer (WL) for the layer-by-layer growth is a few atomic layers in thickness, beyond which quantum dots begin to form.
