My research project centers on the development of the Quantum Material Press (QPress), a cluster tool designed for the high-throughput production and characterization of heterostructure 2D materials. The primary objective is to establish a reliable and efficient method for fabricating 2D materials to benefit 2D research community. 

I am responsible for the design, construction, and oversight of the hardware involved in exfoliating, characterizing, and stacking 2D flakes to create targeted heterostructures. This process has been fully automated and optimized to ensure both high yield and reproducibility. The QPress cluster tool, equipped with three custom modules (exfoliator, cataloger, and stacker) within an inert glovebox, introduces novel opportunities for the 2D materials research community. It facilitates the characterization and fabrication of 2D materials through in-situ and in-line measurement of their structures, ultimately leading to the production of higher-quality 2D materials.
