We focus on synthesis and transport properties of 2D and topological nanomaterials.
2D Layered Chalcogenides
We induce new phases and control properties of 2D layered materials via surface functionalization using organic molecules, intercalation of metal ions, and construction of heterostructures. We are interested in superconductivity, charge density waves, ferroelectricity, and nanoscale phase transformations.
Topological Nanomaterials
We develop precision synthesis of topological nanomaterials and study their transport properties. Our synthesis toolbox includes VLS growth, MOCVD, and thermomechanical nanomolding to make nanostructures to enhance topological surface state properties. Currently, we focus on realizing 1D topological superconductors for robust quantum computing and 1D topological semimetals for next-generation interconnects.
In Situ STEM for phase transformations
We are interested in the dynamic relationship between structure and properties of nanomaterials during phase transformations. At the nanoscale, analysis of the entire structure is manageable using STEM. We apply various in situ TEM techniques and operate nanodevices using our 2D and topological nanomaterials to establish structure-property relations during phase transformations.
