Completed TRL 3 (started at 2, targeting 3)
My research on topological materials at limited dimensions seeks to lay the groundwork for the next generation of magnetic sensors and low-dissipation circuitry. My research focuses on two compounds: WTe2, a type-II Weyl semimetal, and SnTe, a topological crystalline insulator. I plan to use intercalation and doping to tune the unique electrical properties of WTe2 and SnTe at the nanoscale, where the high surface to volume ratio accentuates the contributions from the topologically protected surface states. Additionally, I will develop novel strategies to mitigate the effects of surface oxidation, which degrades the electrical properties of these compounds. In my research, I will link synthesis to material properties through systematic physical, chemical, and electrical characterizations. The proposed applications based on these topological materials align with the main goal outlined in NASA Technology Roadmap TA 10: Nanotechnology to “provide an overall reduction in vehicle mass while enhancing efficiency, performance, and safety.” This research path can be further focused by major area 10.4, “Sensors Electronics, and Devices.” Collaboration with the NASA Visiting Technologist program will allow further investigation into the radiation stability of topological material based devices.

Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
