Plot of the change in the Gibbs thermodynamic potential (ΔG) versus the number (n) of molecules constituting the cluster. ΔG* determines the size of the critical nucleus (n*) and ΔG = 0 determines the size (ng) of the completely stable nucleus, i.e. the crystalline cluster which is predetermined to grow steadily (and is calculated by EBDE).
