Epitaxy

Epitaxy is a type of crystal growth or material deposition in which new crystalline layers are formed with one or more well-defined orientations with respect to the crystalline seed layer. The deposit

Stranski–Krastanov growth

Stranski–Krastanov growth is one of the three primary modes by which thin films grow epitaxially at a crystal surface or interface. Also known as 'layer-plus-island growth', the SK mode follows a two

…during manufacture and handling. Heteroepitaxial growth is classified into three primary growth modes-- Volmer–Weber (VW), Frank–van der Merwe (FM) and Stranski–Krastanov (SK). In the VW growth regime, the epitaxial film grows out of 3D nuclei on the growth surface. In this mode, the adsorbate-adsorbate interactions are…
Figure 4. Evolution of Auger peak height as function of surface coverage during SK growth. The plot is a series of segmented linear curves with a clear break point indicating the critical thickness (clearly marked in the diagram) and the onset of island growth. Slope differences are due to the different modes of growth. The initial steep-sloped segment corresponds to the FM growth mode while the later, shallow-sloped region is representative of the VW mode. This schematic is characteristic of 'ideal' SK growth where nucleation onset begins at 2 monolayer coverage.
