Graphene Imaging and Electronic Properties

honors thesisCollege of EngineeringMechanical EngineeringKeunhan (Kay) ParkThis thesis explores the process required to determine the near-field photocurrent of single- and multi-layered graphene. The experimental procedures for both imaging the graphene as well as collecting data for the near-field photocurrent are described. The imaging and data collection were both to be done using Atomic Force Microscopy, although technical difficulties and time constraints prevented its completion here. However, the first step in the process, essential for the success of future electrical measurements, is imaging the graphene. Results from these efforts are described, along with suggestions for future improvement. This future research will expand the scientific understanding of the electronic properties of single- and multi layered graphene, which is promising for the future use of graphene in electronic devices, including devices that function as an alternative energy source
