Growth processes were performed with gas mixtures of SiH 4 and Ar in a plasma chemical reactor at low pressure. A distinctive feature of presented kinetic model of generation and growth of nanoparticles (compared to our earlier model) is its ability to investigate small "critical" dimensions of clusters, determining the rate of particle production and taking into account the influence of SiH 2 and Si 2 H m dimer radicals. The experiments in the present study were extended to high pressure (!20 Pa) and discharge power (!40 W). Model calculations were compared to experimental measurements, investigating the dimension of silicon nanoparticles as a function of time, discharge power, gas mixture, total pressure, and gas flow.
