PHYS/ASTR Colloquium: "Tailoring the Properties of 2D and Topological Materials from Controlled Synthesis" - Dr. Hui Cai (Asst. Prof., UC Merced)

Tailoring the Properties of 2D and Topological Materials from Controlled Synthesis
Two-dimensional materials have attracted extensive research interests due to their intriguing optical, electronic, and magnetic properties. Pushing these materials toward practical applications requires controllable synthesis methods and facile routes for tailoring their properties on demand. In this presentation, I will show the synthesis of 2D materials and topological materials, such as gallium chalcogenides, transition metal dichalcogenides, and tin chalcogenides, with controlled structure, morphology, and properties from the chemical vapor deposition approach. Multiple routes, including strain engineering, defect engineering, and phase engineering, have been applied to manipulate the physical properties of these materials. Our work provides insights for achieving tunable properties in 2D semiconductors and quantum materials through controlled synthesis.
