This calculation is based upon parameters studied in situ by transmission electron microscopy (TEM), related to the first quantitative study on the nucleation and the growth of Pd\/ MgO(100). The deposited Palladium nanoparticles are tested in the temperature range 573\u20131073 K and deposition time of 1000 s. The nucleation kinetics is interpreted according to the theory of random nucleation. The general scheme is consisting of three stages namely, nucleation, growth and coalescence. The saturation density of clusters decreases when the substrate temperature increases following Arrhenius law. This behavior is in agreement with a recent AFM study for Ag\/MgO and Au\/MgO. The phenomenon of coalescence is explained via island migration process. It is shown that the coalescence occurs more rapidly when the substrate temperature is high.<\/p>\n<p><em>\u00a0<\/em><\/p>\n<p><strong>Keywords:<\/strong> Nucleation, Growth, Simulation, Palladium, MgO (100).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Num\u00e9ro de la revue:\u00a034 Auteurs: Fatma Baara1 &amp; Abdelbaki Chemam2 1Laboratory\u00a0 of surfaces and interfaces of solids studies &#8211; (LESIMS) \u2013Department of Physics, Faculty of Sciences-Badji Mokhtar University-Annaba-Algeria. 2Preparatory School for Science and Technology of Annaba, Annaba 23000, Algeria.
