Directed Nanoscale Transformations of Materials
This theme seeks to understand and control the dynamic changes of chemical and structural states that materials undergo in confined and non-equilibrium conditions by focusing on three specific aims, all of which seek to understand:
- How energy is transferred from an electron or ion beam or scanning probe tip to a material
- Energy and mass transfer at the atomic and molecular scale, and
- The effects of confinement on locally driven chemical reactions, and conversely, how reaction processes and pathways affect the selection and confinement of reaction products.
The starting point for this work is the observation that experimental platforms to visualize structure and function, such as electron, ion, and scanning probe microscopes and associated spectroscopies, can also be used to induce transformation thus enabling the study and the control of the processes of highly localized structural, chemical, and electrochemical changes. The understanding gained here will enable us to direct matter with atomic precision to create 3D nanoscale structures with desired form and function.
