My research focuses on semiconducting and magnetic two-dimensional (2D) materials and their heterostructures for spintronic applications. During my PhD, I studied semiconductors with coupled spin–valley physics (MoS₂, WS₂, and SnS) and magnetic materials (Cr₂Ge₂Te₆, CrSBr, and CrBr₃), along with their heterostructures (WS₂/GaAs and Cr₂Ge₂Te₆/InGaAs).
I aim to expand this work toward developing novel 2D materials and heterostructures that are difficult to obtain via mechanical exfoliation or conventional etching processes. I will explore the synthesis of designer magnetic 2D materials through termination control to realize unconventional magnetic phases.
