A schematic of crystal growth using the Kossel model. The numbering signifies the steps undertaken by the molecule to move from the bulk (1), to diffuse to the solid surface (2), for it along with the surface to dessolvate (3), and finally for it to be incorporated into the solid shown with the black outline (4). The lettering represents the topographical features: a. the terrace, b. the step, and c. the kink site of preferred attachment
