The formation of nuclei and clusters from single atomic or molecular species plays an important or even decisive role in laser-induced (gas-phase) synthesis of powders, laser-CVD, etc. Of similar importance are (heterogeneous) nucleation processes in laser-annealing, recrystallization, thin-film formation, etc. Depending on the particular application, nucleation and cluster formation can be desirable or undesirable. An example of the latter case is pulsed-laser deposition (PLD) where clusters formed within the vapor plume may condense on the substrate and thereby deteriorate the film quality.
