Crystal growth: definition. The linear growth rate is the rate of growth of a face in the direction normal to the face: velocity in the internal coordinate. Growth is a kinetic phenomenon driven by supersaturation ( > 1), that is determined by the thermodynamic data. Growth occurs independently for each face in layer-by-layer …What all crystals have in common is an extremely well-organized molecular structure. In a crystal, all of the atoms (or ions) are arranged in a regular grid pattern. For example, in the case of table salt (NaCl), the crystals are made up of cubes of sodium (Na) ions and chlorine (Cl) ions. Each sodium ion is surrounded by six chlorine ions.The templates for Crystal Growth & Design are available below. While authors are encouraged to use an ACS template, it is not mandatory.
