Research Activities

My research project is focusing on developing a new cluster tool for high-throughput production and characterization of heterostructure 2D materials. My main task in this project is designing and building instrumentation. I will oversee the assembly of hardware for handling/stacking 2D flakes to fabricate target structures. The process will be completely automated and optimized for high reproducibility. I will work on integrating the cluster tool modules for characterization and fabrication for in-situ and in-line measurement of the target structures, which enables us to fabricate better quality 2D materials. The ultimate goal is to provide a reliable and efficient method of 2D material fabrication to CFN users.
