Wurtzite Ferroelectrics Reach 10 Billion Switching Cycles by Confining Nitrogen Vacancies
Key Takeaways
- A Science paper (Vol. 393, Issue 6816, pp. 1134–1138, September 2026) reports endurance beyond 10 billion cycles in wurtzite ferroelectrics.
- The mechanism named in the title is confinement of nitrogen vacancies, the mobile point defects that degrade polarization switching.
- Nitrogen vacancies can screen applied fields and pin domain walls, driving the reliability decay that limits ferroelectric memory.
- The reported endurance figure is the order of magnitude relevant to write-heavy embedded memory and in-memory computing.
