| Abstract Scope |
Alkali species (e.g. Li, Na, and K) play important roles in many technological applications, ranging from glass science to batteries and nuclear reactors. Their importance in these applications originates in part from their unique group chemistry, which also results in unique challenges for their characterization by some analytical techniques. As an example, atom probe tomography is a powerful 3D analytical technique that relies on field evaporation at cryogenic temperatures to controllably remove and reconstruct atomic positions and identities. For alkali species, this process is complicated by their relatively low evaporation field and high surface diffusivities. In this poster, I will outline out strategies for approaching the characterization of alkali species via atom probe tomography, the current limitations of these methods and corresponding analyses, and potential paths forward for further improving the method and understanding of alkali distributions in a variety of materials systems. |
