Abstract

The influence of annealing dynamics on the size and orientation of copper foil grains used for graphene synthesis at chemical deposition from the gas phase was studied. Annealing was carried out in argon and hydrogen atmospheres setting a constant temperature profile on the processed substrate and temperature gradient along the substrate. The temperature range and times were chosen in accordance with the regimes effective for graphene synthesis. It was shown that hydrogen has a significant effect on the growth of grains. Orientation of large grains, formed on the copper surface due to secondary crystallization, was random in the studied regimes.
