A model of thermally activated crystal growth is a foundation for theory of crystallization.
In the model of thermally
activated crystal growth addresses to the elemental act of incorporation of molecule on the surface into crystal. In the spite
(or because) simple mathematical formulation ...
An observation of the crystals growing with flat surfaces and in the same time difficulty of quantitative application
of the two dimensional nuclei model for quantitative explanation of experimental data for temperature dependence of rate
of crystal growth as well an occasional the observation spira...
One of the models of layer by
layer growth of crystal is based on the random process of forming two
dimensional nucleus that schematically displayed on the following picture:

The model of thermally activated crystal growth as described in
the article leaves aside the very important feature of crystal growth phenomena
namely the influence
of surface energy.
A difference in levels of free energy between molecule situated at the
surface of the crystal incorpora...
