Understanding and Controlling the Electronic Properties of Graphene Using Scanning Probe Microscopy
Abstract
This project has been focused on understanding and controlling the electronic properties of graphene using scanning tunneling spectroscopy and optical spectroscopy. By using boron nitride as a substrate underneath graphene we have significantly improved the device quality. We have found that the periodic potential from the boron nitride can modify the band structure of the graphene. The boron nitride also changes the Raman spectrum of the graphene. We have also explored the role of adding additional layers to graphene and different stacking configurations. A third aspect of the project has studied modification of the graphene band structure through femtosecond laser pulses.
