Seeking Answers in Ferroelectric Patterning
Why do some ferroelectric materials display bubble-shaped patterning, while others display complex, labyrinthine patterns?
Thin-film ferroelectric materials display characteristic, evolving patterns
A FLEET study finds the answer to the changing patterns in ferroelectric films lies in non-equilibrium dynamics, with topological defects driving subsequent evolution.
Ferroelectric materials can be considered an electrical analogy to ferromagnetic materials, with their permanent electric polarisation resembling the north and south poles of a magnet.
Understanding the physics behind their domain-pattern changes is crucial for designing advanced low-energy ferroelectric electronics, or brain-inspired neuromorphic computing.
LABYRINTHINE VS BUBBLES: WHAT PATTERNS REVEAL
The characteristic domain patterns of thin-film ferroelectric materials are strongly influenced by the type of materials, and by the film configuration (substrate, electrod
