The following are some suggested questions for everyone to think about:
  1. To date, only tenuous examples of room temperature topological effects have been reported. It this simply a materials quality problem or a matter of discovering a new topological material, or are there fundamental constraints that are not widely discussed? How well do we understand the physics and chemistry that may enable “room temperature” topological behavior?
  2. Experts have been continuously searching for any combinations of stable or metastable single phase compounds/alloys for topological properties with prominent theoretical groups developing models and databases to guide exploratory studies for new topological materials. Do you expect the bismuth dichalcogenide family to remain the most prominent of the 3D topological insulators? Should the push for room temperature topological materials be aggressively pursued? If so what strategy do you recommend?
  3. Besides single phase materials, will “hidden phase” or “multiple phase” matter be a promising space to explore? How do we define the phase at a hetero-interface?
  4. Can and should the semiconductor surface science of the 1970s and 1980s be duplicated within topological materials? Can a surface\interface science that includes atomic-level spin structure be developed?
  5. What new growth and characterization inventions are needed to propel the field of topological materials?
  6. Is current State of the Art computation capability providing sufficient “fidelity” to enhance our understanding of the physics of topological materials and their heterostructures with materials with various order parameters? Are there problems that are not solvable with today’s computational infrastructure and if so, what sort of advances are necessary?
  7. In semiconductors, carrier transport characteristics like mobility, fermi velocity and minority carrier lifetime are key factors to determine the suitability of a material for electronic devices. Do we have an idea of the carrier dynamics in topological materials and how it relates to proposed device concepts?
  8. Though topological materials are reviving spintronic concepts, it is essentially impossible to compete with more than half a century of technological refinement in semiconductor devices either for logic or memory. What technology space is most likely to be impacted by advances in topological materials? Any thoughts about how best to get there? Does increased interest in cryogenic computing give topological materials an opportunity?
