The Stransky-Krastanov growth mode , also known as the layer-by-plus-island growth mechanism, is one of the three main mechanisms for the growth of thin films; describes the case when growth begins as two-dimensional ( layered ), and then changes to three-dimensional ( islet ). Named in honor of the Bulgarian physicochemists Ivan Stransky and Lubomir Krystanov .
Description
Layer-by-layer-plus-island growth according to the Stransky-Krastanov mechanism is an intermediate case between layer-by-layer and islet growth. After completion of the formation of the two-dimensional layer, three-dimensional islands grow. The nature and thickness of the two-dimensional layer (often called the Stransky-Krastanov layer) depends on the particular case. For example, this layer can be a surface reconstruction with a submonolayer adsorbate coating or a strained film with a thickness of several monolayers.
