The paper explores the effects of thermal vibrations on the acceleration of atoms during a surface phase transition which occurs via the coherent energy transfer mechanism from many adatoms initially in metastable states to a single accelerated adatom. The acceleration is the result of a long chain of subsequent collisions with a single particle harvesting the energy of the transition of its predecessor in the chain. The paper presents the analysis of the stability of the suggested system, simulation of the dynamics of the accelerations and the analysis of the limits imposed on the process by defocusing and scattering on thermal vibrations.
