Research on new materials and functional devices has led to fundamental changes in our daily life for the past several decades. Two-dimensional (2D) crystal materials with atomic thickness, such as graphene, complex oxides, and transition metal chalcogenides (TMCs), have become a broad playground where the interface effects and quantum confinement can lead to substantial modifications in their electronic and magnetic properties. Novel physical phenomena often emerge when stacking or growing the 2D materials on various substrates, or imposing quantum confinement in the lateral or vertical dimension.
We aim to achieve scientific and technological breakthroughs utilizing such high tunability of the properties of the 2D crystals. The research in my lab integrates molecular beam epitaxy (MBE) synthesis, one of the most sophisticated synthesis techniques for the growth of materials with atomic-scale precision, with nanostructure fabrication and a variety of characterization techniques for physical and electronic structures to explore and control the generated properties in new materials and in new forms of materials, such as in heterostructures and gated field effect transistors (FETs). A collaboration with Professor Andrea Damascelli’s group allows us to perform in situ angle-resolved photoemission spectroscopy (ARPES) that maps band structure and Fermi surface with superior resolution.
I am currently looking for motivated undergraduate/graduate students and postdoctoral fellows.
