Two-dimensional Nanomaterials
Stacking of 2-dimensional nanomaterials offer state-of-the-art performance metrics. Novel, high-throughput techniques to realize ultra-clean, dry-transferred 2D material heterostructure are highly sought-after to enable advanced material technologies.
In this project, we explore a novel approach to perform microfabrication of clean, 2D material heterostructure to enable high performance graphene-based sensor applications. We perform CVD synthesis of graphene films and their quality characterization using Raman spectroscopy. Using chemical vapor deposition (CVD), the mass-production of graphene films for industrial applications is achievable today. Current progress in standardization of graphene & 2D material quality is encouraging for the development of industrial applications using graphene films. Several type of graphene-based use case applications are explored during the project.
