Characterization of 2D Heterostructure Graphene and Transition Metal Oxides

Two-dimensional materials with transition metal oxide heterostructures show a growing potential for a wide amount of uses in electronics including single molecule gas detectors and transistors. Due to this rising interest, the need to further understand the material properties has become a priority. The goal of this study is to further the understanding of the electronic, magnetic and structural properties of transition metal oxides interfaced with graphene. This will be accomplished by using a pulse laser depositioning method to synthesize micro-thin layers of molybdenum-oxide (MoOx) onto a silicon wafer (Si and SiO2). Then by applying a dry transfer exfoliation technique, a film of graphene will be applied. The methods of studying the material include Raman spectroscopy for determining structural properties, IV characterization for electrical properties, Photoluminescence Spectroscopy for understanding semiconducting properties, and X-Ray diffraction for crystal structures.
