Nb2O5 纳米管内产生多个 NaNbO3 纳米板，形成结合铁电和半导体纳米材料的独特异质结构纳米管。 NaNbO3 纳米片的局部压电研究显示出明显的铁电行为（见图），而主体 Nb2O5 纳米管的半导体特性允许通过外部电场切换电导率。
Multiple NaNbO3 nanoplates are created within Nb2O5 nanotubes forming a unique class of heterostructure nanotubes combining ferroelectric and semiconducting nanomaterials. Local piezoelectric studies on NaNbO3 nanoplates show clear ferroelectric behavior (see figure), while the semiconductive properties of the host Nb2O5 nanotubes allows for switching of the electrical conductivity by an external electric field.
