Abstract:
Graphene is a new two-dimensional material that has many interesting properties due to its low energy excitations which behave as Dirac fermions. To unlock its application potential, it is necessary to study the electronic transport in graphene samples that are disordered or functionalized. This is partly due to the fact that pristine graphene is costly to prepare, but some application aspects also depend on the controlled functionalization of graphene and the resulting change in the electric conductivity, such as graphene gas sensors. This dissertation discusses four topics related to functionalized graphene systems and their electronic transport behavior.
