Abstract
In this thesis the properties of graphene and its few-layers are engineered to make them
highly conductive. Two different approaches were implemented to achieve this goal.
One approach was to increase the concentration of charge carriers by intercalation of
acceptor FeCl3 molecules between graphene planes. This resulted in a highly conductive
yet transparent material which can be useful for applications. Another approach
was to increase the mobility of carriers by means of removing surface contamination
in the current annealing process. Optimal annealing parameters were found and a
reproducible cleaning method was suggested
