Integrated Multi-Scale Modeling of Diamond Chemical Vapor Deposition
The fundamental mechanisms of diamond growth occur on the atomic scale. However, the geometry of the deposition reactor and the other operating parameters directly affect the chemical composition of the gas and the temperature at the growth surface. The properties are in turn controlled by both atomicand microstructural-scale features. By developing diamond growth models at each length scale an...
متن کاملSimulation of morphological instabilities during diamond chemical vapor deposition
The diamond chemical vapor deposition (CVD) process has been investigated theoretically and the morphological instabilities associated with the growth of diamond films have been examined with a model based on the continuum species conservation equation coupled to surface reaction kinetics. A linear stability analysis and numerical calculations have been carried out to determine critical paramet...
متن کاملUnderstanding the chemical vapor deposition of diamond: recent progress.
In this paper we review and provide an overview to the understanding of the chemical vapor deposition (CVD) of diamond materials with a particular focus on the commonly used microwave plasma-activated chemical vapor deposition (MPCVD). The major topics covered are experimental measurements in situ to diamond CVD reactors, and MPCVD in particular, coupled with models of the gas phase chemical an...
متن کاملPlasma-enhanced chemical vapor deposition of nanocrystalline diamond
Nanocrystalline diamond films have attracted considerable attention because they have a low coefficient of friction and a low electron emission threshold voltage. In this paper, the author reviews the plasma-enhanced chemical vapor deposition (PE-CVD) of nanocrystalline diamond and mainly focuses on the growth of nanocrystalline diamond by low-pressure PE-CVD. Nanocrystalline diamond particles ...
متن کاملInfrared properties of chemical-vapor deposition polycrystalline diamond windows.
Low-resolution transmittance and reflectance spectra of high-quality chemical-vapor deposition (CVD) diamond windows were measured in the infrared in the 2.5-500-mum wavelength range (20-4000 cm(-1)). High-resolution measurements on a window with nearly parallel surfaces show well defined interference fringes at low frequencies. By standard procedures the optical constants n and k of CVD diamon...
