## Abstract

Non-technical abstract:
Topological materials are a unique set of materials that conduct electrons differently on their surfaces than they do throughout their bulk. This leads to interesting and unique transport properties and potential to unlocking a new generation of efficient solid-state energy conversion devices. Results of this project will help gain fundamental understanding of the properties of topological materials, allowing their synthesis with most useful properties and usable forms while preserving their unique attributes. This approach is likely to ultimately enable a new class of efficient energy conversion devices based on strategically designed topological materials. This project also humanizes the fundamental concepts of charge carrier transport through extensive set of outreach and education activities. The research team uses a physical embodiment of charge carrier motion to explain it to a broad general audience and uses creative ways of conveying these concepts and inspiring interest in science.

Technical abstract:
While transport properties of topological materials have strong potential for use in efficient solid-state devices, little progress has been made moving towards their use due to challenges in designing and synthesizing topological material in useful forms. Crucial to this progress is understanding the critical length scales over which topological transport dominates, eliminating stray magnetic fields and reducing externally applied magnetic
