Abstract

This PhD thesis focuses on the understanding and the control of the nanocrystalline diamond (NCD) film growth process by distributed antenna array microwave plasma-assisted chemical vapor deposition. Two approaches were followed to reach these objectives: a « material » study aiming at studying the nucleation and growth mechanisms and the characteristics of the synthesized NCD films; a « plasma » study focusing on the diagnostics of H₂/CH₄/CO₂ low-pressure discharges used for NCD growth.Concerning the first part of this work, ex situ characterization techniques, such as scanning and high resolution transmission electron microscopy, atomic force microscopy, Raman spectroscopy, X-ray diffraction, UV-visible reflectometry, and in situ, such as...
