Homoepitaxial CVD diamond growth
In this tutorial, we will discuss physical and chemical aspects of homoepitaxial CVD diamond growth, through different models commonly used. The influence of CVD process control parameters on the vapour phase properties and their consequences on the growth and film characteristics will be presented. The effect of the substrate on homoepitaxial diamond growth will also be considered.
In the second part of the tutorial, we will examine the relevant parameters governing the morphology of the growing crystals and we will introduce the difference between growth morphology and steady-state morphology. The influence of CVD growth parameters on these morphologies will be explained.
Lastly, the mechanisms responsible for the formation of structural defects within the diamond films during growth will be detailed and certain recommendations will be given in order to limit their occurrence. Francois Silva, University Paris 13, France |
