Outline of Final Research Achievements

We have studied the formation processes of carbon dust using the small experimental setup which we have been designed and built. The micron sized carbon dusts have been observed in the designed experimental setup after hydrogen plasma discharge. Almost of all carbon dusts have a spherical shape which are of the order of micro meter. The images of cross sections of carbon dusts observed by an electron scanning microscopy have indicated that the carbon dusts growth by columnar growth. The infrared spectroscopy have been adopted to observe the dynamic formation of carbon dusts. The experimental results have indicated that spectra of infrared spectroscopy have large amount of noise. The reduction of noise in infrared spectroscopy require to observe the dynamic growth of carbon dusts in the experimental setup.
