| Abstract Scope |
Powder aerosol deposition, in particular, enables the rapid creation of thick films without high-temperature processing, significantly reducing production
cost and time compared to traditional methods. However, challenges remain in optimizing functional properties due to internal stresses, increased conductivity in insulators, and nanograined microstructures. Ongoing research focuses on understanding the mechanisms of film deposition and adhesion, as well as controlling defects at grain boundaries that contribute to the films' non-equilibrium state. Thermal treatments and atmospheric control offer potential solutions to relax these defects and improve film performance. Additionally, the mechanical response of ferroelectric materials is critical, necessitating the development of methods to characterize deposition stress and local residual stress states. This presentation underscores the potential of room temperature fabrication techniques for producing functional ceramic films, highlighting the importance of overcoming current limitations to fully realize their capabilities in various technological applications. |
