Abstract:
This thesis describes an alternative approach to graphene research. It puts forward that the concept of graphene as a "miracle" material largely differs from the reality. The thesis describes high-resolution characterisation of commonly seen imperfections in graphene and a new application for graphene that overcomes such defects. The thesis is divided into two main areas; high-resolution transmission electron microscopy (HRTEM) characterisation of naturally occurring defects in CVD graphene; and the synthesis and transfer of CVD graphene for the creation of the first graphene surface force balance (gSFB). The HRTEM work focuses on the thorough characterisation of "real" graphene and hence analyses the quality of the graphene that is likely to be used in research laboratories and industry. The creation of the gSFB has not only provided an instrument for novel surface force measurements of graphene but has also provided a new ultra-smooth transfer technique which can be further used elsewhere. The work undertaken in both of these areas is beneficial, not solely in graphene terms, but also for other 2D materials. For example, the gSFB has the potential to be altered to measure 2D chalcogenides and hBN interactions, and similar high-resolution characterisation of common defects in other 2D materials will also provide information on their synthesis, transfer and hence feasibility of industrial production. The research in this thesis is positioned between the pristine, flawless graphene portrayed in the literature, and the real material which will eventually be used in applications on the larger scale.
