AI 中文摘要
铁电向列型液体展现出由弹性与静电相互作用竞争形成的复杂铁电畴。我们利用荧光和偏光显微镜，研究不同锚定条件下的畴形成与演化，带电荧光离子绘制出静电势，揭示电场局域在畴壁和材料表面附近。冷却时，畴壁从伊辛型转变为奈尔型构型，降低了静电势，加热时可逆恢复。
英文摘要
Ferroelectric nematic liquids exhibit complex ferroelectric domains shaped by competing elastic and electrostatic interactions. Using fluorescence and polarizing optical microscopy, we investigate domain formation and evolution under different anchoring conditions. Charged fluorescent ions map the electrostatic potential, revealing that electric fields are localized near domain walls and material surfaces. Upon cooling, domain walls transform from Ising- to Néel-type configurations, lowering the electrostatic potential, and reversibly recover upon heating.
