During this time, I performed cryogenic electronic transport as well as optoelectronic measurements on twisted bilayer graphene systems. The subjects I studied are

• Electronic transport properties of magic-angle twisted bilayer graphene with high-k dielectrics
• Layer circular photogalvanic effect in large-angle twisted bilayer graphene

During this time I did a series of study on STM/STS spectroscopy of strongly correlated quantum liquids in transition metal dichalcogenides heterostructures, and electrical engineering work on 2D materials fabrication. They are

• Tunable Luttinger liquid systems in TMD heterostructures

• Semi-automated transfer stage in glove box

• Coordinate-encoded on-chip QR code for STM measurement

During this time I learned the basic ab-initio DFT calculations and some strongly correlated phenomenologies about CDWs in 2D TMDs. I worked on

• First-principle calculations of transition metal dichalcogenides

During this time I worked on a series of theories on Floquet topological materials. Specifically, I studied

• Anomalous Floquet higher-order topological insulators
