Abstract:
To miniaturize functional devices, electroceramic components must be reduced in size down to the micrometer range. Screen printing and aerosol deposition methods offer a cost-effective way to deposit piezoelectric layers with a thickness of a few micrometers to a few tens of micrometers on various substrates. While the piezoelectric performance of thick films is typically examined at a macroscopic scale, there are not many reports on how the piezoelectric response varies with film thickness at a microscopic level. In this investigation, we develop a method to study films in cross-section by piezo-response force microscopy. To demonstrate the usefulness of a newly developed setup for studying the ferroelectric domain structure of films in cross-section, lead-based and lead-free films were prepared by screen printing and aerosol deposition methods. All films were macroscopically piezoelectric and therefore a suitable candidate for investigating their local piezoelectric response across their thickness.
