Coupled Field-Gated Nucleation and Autocatalytic Growth in Ferroelectric Switching
- 1Independent Researcher
Abstract
Polarization switching in fluorite (HfO2, Hf0.5Zr0.5O2) and wurtzite (AlScN) ferroelectrics is dispersive: nominally identical devices and domains switch over a spread of time rather than at a single threshold. The nucleation-limited-switching (NLS) model treats this phenomenon as a Lorentzian-in-log-time distribution of nucleation waiting times; Kolmogorov–Avrami–Ishibashi (KAI) theory instead treats switching as deterministic nucleation-and-growth. Recent AlScN transport studies report devices moving between these regimes in terms of defect density, thickness, or cycling, motivating a model in which nucleation and growth are explicit, coupled, field-dependent processes.
