A model is proposed for the formation of spherical and treelike particles during the growth of diamond films by chemical vapor deposition (CVD) using a direct current electric discharge to activate. Spherical diamond particles are formed when the surface energies of different diamond faces are equal, which arises during growth with a certain temperature, depending on the parameters of the gaseous medium. The growth of tree particles is created by the movement of charged particles along the lines of the electric field.
