Abstract
The time evolution of polarization state of Mie-scattered light from carbon particles trapped in a methane plasma was measured by a newly developed ellipsometric method. By comparison of the experimental results with a model simulation, it is found that the particles grow by coating with hydrogenated amorphous carbon. It is also found that they have been isotropically and equally coated independent of their initial shape and diameter without homogeneous nucleation and that spherical and monodisperse particles have grown consequently.
