Special Issue Information

Dear Colleagues,

We would like to invite you and appreciate your contribution to this Special Issue of Coatings entitled “Advances in Ferroelectric and Piezoelectric Thin Films: Synthesis, Properties, and Applications”.

Functional materials like ferroelectrics and piezoelectrics find a wide range of applications, including memories, radio frequency and microwave devices, pyroelectric, piezoelectric sensors and actuators, photovoltaic, and in many other systems. The understanding and integration of functional materials into devices require a multidisciplinary approach encompassing the ideologies across various fields of physical science and engineering. There has been an unprecedented advancement in theoretical and computational models, synthesis, and characterization, thereby enabling researchers to explore the recently recognized applications of ferroelectric and electromechanically active materials—from high energy storage devices to flexible energy harvesting systems. Environmental concern along with miniaturization and integration of electronic devices is escalating the need for new, sustainable, and improved materials.

This issue aims to summarize the recent advances in thin film and nanoscale ferroelectric and piezoelectric materials, with subject matters ranging from synthesis, growth, their related functional properties, and device fabrication. Authors are invited to submit original research, critical review articles, or short communications focused on but not limited to these topics:

  • Lead-free piezoelectric;
  • Flexible mechanical/piezoelectric energy harvesters;
  • Pyroelectric and electrocaloric effect;
  • Ferro/piezoelectric polymer nanocomposites;
  • Ferroelectric thin films for high energy storage devices;
  • Domain structure and local piezoelectric properties;
  • Domain and domain wall engineering;
  • Thin films of organic and MOF ferroelectrics.

Chemical solution deposition of BiFeO3 thin films is one of the most commercially available techniques to produce large-scale low-cost coatings for further application in memory devices. In this contribution, we implemented piezoresponse force and conductive atomic force microscopies to study the layer-by-layer sol-gel deposition of BiFeO3 thin films focusing on the local phase distribution, morphology, piezoelectric response, and leakage current. The final properties of resulting thin films are found to be determined not only by the composition of the gel and crystallization step but by the gelation step as well. The drying temperature and treatment duration of the solution are shown to drastically influence the film coverage, which finally determines the morphology of the films and behavior of the crystallization process.

Layered piezo-composite unimorph actuators have been studied by many research teams to provide active vibration control of thin-walled aerospace structures, control the shapes of aircraft wing airfoils, and control the fins of small missiles, because they require less space and provide better frequency responses than conventional electro-magnetic motor actuator systems. However, due to the limited actuation strains of conventional piezo-composite unimorph actuators with poly-crystalline piezoelectric ceramic layers, they have not been implemented effectively as actuators for small aerospace vehicles. In this study, a lightweight piezo-composite unimorph actuator (LIPCA-S2) was manufactured and analyzed to predict its flexural actuation displacement. It was found that the actuated tip displacement of a piezo-composite cantilever could be predicted accurately using the proposed prediction model based on the nonlinear properties of the piezoelectric strain coefficient and elastic modulus of a piezoelectric single crystal.
