摘要

铁电材料：该图像突出显示了应变Ba(Zr,Ti)O3薄膜中多晶纳米畴的方位和偏振分辨二次谐波（SHG）映射。在文章2500278中，任宇航及其同事报道了LaAlO3衬底的外延应变打破了面内对称并诱导了各向异性畴结构，从而实现了四方相和方面体相的空间识别。这种非线性光学方法揭示了对铁电器件性能至关重要的局部应变场。

Ferroelectric Materials

The image highlights azimuth- and polarization-resolved second harmonic generation (SHG) mapping of polymorphic nanodomains in strained Ba(Zr,Ti)O₃ thin films. In article number 2500278, Yuhang Ren and co-workers report that epitaxial strain from LaAlO₃ substrates breaks in-plane symmetry and induces anisotropic domain structures, enabling spatial identification of tetragonal and rhombohedral phases. This nonlinear optical approach reveals local strain fields critical to ferroelectric device performance.
