研究了应力载荷对铁电纳米片涡域结构的影响。相场模拟结果表明，在随机扰动下，独立纳米片可以形成不同的涡域结构。在纳米片上施加应力载荷，发现纳米片的畴形态，特别是漩涡的大小和数量是可以有规律地控制的。这些结果表明，利用机械载荷控制铁电纳米结构中的涡域结构是有希望的。
Effect of stress loads on the vortex domain structures (VDSs) in ferroelectric nanosheet has been investigated. Results of phase field simulations show that the different vortex domain structures can form in free-standing nanosheet from random perturbations. Applying stress loads on nanosheet, it is found that the domain morphology, especially the size and number of vortices, can be regularly controlled. These results indicate promising controlling the vortex domain structures in ferroelectric nanostructures by the mechanical loads.
