The
energy required to overcome the activation
barrier for nucleus formation comes from lattice thermal fluctuations
and is governed by the Boltzmann
relationship
for the Probability of ΔGhet*: PHet= exp {- ΔGhet*(T)/ kT} · The lower value of ΔG* for heterogeneous nucleation, exponentially favors this nucleation process over homogeneous nucleation. |
