Abstract
This paper investigates the quantifiable effects of reactor geometry on the quality of CVD diamond films. This detailed experimental study includes two types of reactor geometries: the 5Â in. quartz dome with 3Â in. substrate reactor and the 4Â in. quartz dome with 2Â in. substrate reactor geometry. More specifically, a comparison between the output variables of both reactor geometries is examined and a complete analysis is presented. The reactor output variables include film morphology, structural quality as measured by Raman spectra and scanning electron microscopy (SEM) techniques, linear growth rate, carbon conversion efficiency, and specific yield. The study shows the impact of variation in the reactor geometry is significant on film morphology, particularly at low temperatures, weight gain, and carbon conversion efficiency. On the other hand, FWHM, linear growth rate, and normalized carbon conversion efficiency are not significantly affected by the reactor geometry.
