Starting with the principle of crystal growth minimum surface energy, it could get the result that the crystal linear growth rate is proportional to the crystal plane specific surface free energy, in which the corresponding relations conforms to the Gibbs - Ulf law of crystal growth.

In formula (1), Ai is the i-th crystal plane specific surface free energy, and Ri stands for the vertical distance from the crystal center towards the i-th crystal plane. Gibbs - Ulf law shows that the bigger the specific surface free energy of the crystal plane is, the corresponding growth rate is faster.

It can be inferred based on the principle of crystal growth minimum surface energy that the linear growth rate of crystal is proportional to the specific surface free energy of the corresponding crystal face, conforming to the Gibbs - Ulf law of crystal growth.

In formula (1), Ai represents the specific surface free energy of the i-th crystal face; Ri represents the vertical distance from the crystal center to the i-th crystal face. Gibbs - Ulf law shows that the higher the specific surface free energy of the crystal plane, the faster the corresponding crystal growth.
