520 ▼a 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
520 ▼a The localization properties of graphene adatoms is studied in chapter 2. Green's function perturbation theory is applied on a general tight-binding model of graphene with adatoms and the energy and the decay of the wavefunction of the impurity s
520 ▼a The data of graphene and carbon nanotube gas sensing experiments is analyzed in chapter 3 with the kinetic Langmuir model adapted to include adsorption sites from which the molecule does not desorb. The model reproduces the available experimenta
520 ▼a In chapter 4 we explore an alternative mechanism for the conductance change in graphene gas sensing. Charged functional groups and dipolar molecules on the surface of graphene may counteract the effect of charged impurities on the substrate. Thi
520 ▼a In chapter 5 we explore another possible explanation for this phenomena assuming that NO chemisorbs to vacancies and eventually dissociates. We found that adsorption of NO in graphene vacancies is favorable by 5.3 eV. In order to evaluate the co
