设计了一种基于二维 (2D) 层状氧化物的新型垂直排列纳米复合材料 (VAN) 结构，并在 LaAlO3(001) 和 SrTiO3(001) 基板上自组装。微观结构分析证明，新的 VAN 结构由嵌入 Bi2WO6 基体中的外延生长的 Co3O4 纳米柱组成，具有独特的二维层状结构。物理性能测量表明，新的Bi2WO6-Co3O4VAN结构在室温下表现出很强的铁磁和压电响应以及各向异性介电常数响应。这项工作展示了一种基于层状氧化物系统的多功能 VAN 结构处理的新方法，面向未来的非线性光学、铁磁体和多铁性材料。
A new vertically aligned nanocomposite (VAN) structure based on two-dimensional (2D) layered oxides has been designed and self-assembled on both LaAlO3(001) and SrTiO3(001) substrates. The new VAN structure consists of epitaxially grown Co3O4nanopillars embedded in the Bi2WO6matrix with a unique 2D layered structure, as evidenced by the microstructural analysis. Physical property measurements show that the new Bi2WO6-Co3O4VAN structure exhibits strong ferromagnetic and piezoelectric response at room temperature as well as anisotropic permittivity response. This work demonstrates a new approach in processing multifunctional VANs structure based on the layered oxide systems towards future nonlinear optics, ferromagnets, and multiferroics.
