Research in WeaverLabs focuses on the properties of surfaces, interfaces and nanostructured materials. The atoms in these systems can be arranged differently from those of bulk materials, and there are unique chemical and physical properties because of their reduced dimensionality. We are interested in the implications of those atomic arrangements.
With high resolution scanning tunneling microscopy, we can visualize (and then develop an understanding of) surfaces and nanostructures in real space, often as they evolve dynamically at elevated temperature or are immobilized at very low temperature.
Using a novel growth technique that we developed, buffer-layer-assisted growth or BLAG, we produce nanostructures of a wide range of materials and explore their interactions when they come into contact, coalesce and are encorporated in composite structures. Electron microscopy plays an important role in these studies.
