Moving Beyond the Spherical Cow: Sputtering in 3D
Gabriel Veith - ORNL

Gabriel M. Veith, Oak Ridge National Laboratory, Oak Ridge, TN
In vacuum deposition we often focus on flat surfaces but what if we could grow materials on a three-dimensional powder? In this presentation we will discuss the growth of conformal sputter deposited coatings grown on irregular high surface area material as well as confined nanoparticles. Particular emphasis will be placed on understanding the nucleation and growth of the deposited species and parameters that affect coarsening of the adatoms. Examples will be presented from lithium ion conducting ceramics and metallic nanoparticles where the deposition was reproducible and uniquely modified the interfaces in ways that could not be done using traditional solution approaches.
