Relative face growth rate, calculation

Several methods exist to calculate relative growth rates. The earliest and simplest of these was initially proposed by Bravais [29] and Friedel [30] and later extended by Donnay and Marker [31]. Known as the Bravais-Friedel-Doimay-Harker (BFDH) model, it states that the growth rate of a given crystallographic face with Miller indices (hkl) is proportional to the inverse of the interplanar distance between... 

The attachment energy model first published by Hartman and Perdok in 1955 [32] specifically accounts for the intermolecular interactions in the crystals when calculating relative growth rates. The growth rate of a crystal face is proportional to the attachment energy, which in turn can be calculated from the lattice energy...
