The growth of graphene by molecular beam epitaxy from an elemental carbon precursor is a very promis- ing technique to overcome some of the main limitations of the chemical vapour deposition approach, such as the possibility to synthesize graphene di

Theoretical Modeling of Epitaxial Graphene Growth on the Ir(111) Surface

Autor: Holly Alexandra Tetlow

One possible method of producing high-quality graphene is to grow it epitaxially; this thesis investigates the mechanisms involved in doing so. It describes how the initial stages of growth on the Ir(111) surface are modelled using both rate equation

As previously mentioned there are two main types of epitaxial graphene growth: temperature programmed growth (TPG) and chemical vapour deposition (CVD). The main difference between these is that in TPG the carbon source (such as hydrocarbon molecules

Density functional theory methods allow for the calculation of the total energy of a system of atoms and the forces acting on the individual atoms. Finding these forces allows the relaxation of structures to their lowest energy structure by driving t

Beginnings of Growth: Carbon Cluster Nucleation

In this chapter the nucleation of carbon clusters on the Ir(111) surface is studied. This process is important in the early stages of graphene growth, where the growth begins with the nucleation of small carbon clusters from carbon monomers, which th
