What is it about?
We here demonstrate a new approach to fabricating porous ferroelectric films with tunable fine porous structures by carrying out sol–gel reactions involving nonionic surfactants. We have found out that Brij-type surfactants can be used to prepare PZT films with uniformly distributed fine pores and a columnar-grain perovskite structure.

Why is it important?
Our approach enables PZT films to be prepared with porous structures optimized for specific applications in electronic devices.
