DC-THz Properties of Graphene-Complex-Oxide Metamaterials
Abstract
Title: DC-THz Properties of Graphene-Complex-Oxide MetamaterialsObjective:To understand the unique properties of graphene-complex oxide (GCO) heterostructures in the DC-THz range, and develop the basis for reconfigurable, engineered devices. This basic research combined with device development will help lay the foundation forinformation processing and sensing applications, with a focus demonstrating key properties that could motivate further development. PI proposes to explore more fully the properties of these unique hybrid electronic systems, focusing mainly on the novel properties that result from the intimate coupling between these two conducting layers.Approach:PI will explore more fully the properties of the unique graphene-complex-oxide (GCO) hybrid electronic systems, focusing mainly on the novel properties that result from the intimate coupling between these two conducting layers. While there will be some effort directed toward improving the processing (e.g., reducing graphene ~wrinkles~), the main emphasis will be to produce GCO heterostructures and probe~through transport and THz spectroscopy~their properties. PI will search for the most interesting and novel phenomena, while staying attuned to the potential for future technological development.SOW:Specific research tasks include:Task 1: Develop GCO Structures1.1 Produce Ultraflat Copper and Graphene1.2 Complex-Oxide Heterostructure Growth1.3 Further develop grapheme transfer technique using Hyflon1.4 GCO Processing1.5 Perform conductive AFM lithography on GCO1.6 Make lithographic contacts to graphene and LAO/STOTask 2: DC Characterization of GCO Structures2.1 DC Transport Characterization2.2.
