  • Title: KTa0.6Nb0.4O3 ferroelectric thin film behavior at microwave frequencies for tunable applications.
    Author: Laur V, Rousseau A, Tanné G, Laurent P, Députier S, Guilloux-Viry M, Huret F.
    Journal: IEEE Trans Ultrason Ferroelectr Freq Control; 2006 Dec; 53(12):2280-6. PubMed ID: 17186908.
    Abstract:
    In this study about the relationships between structural and microwave electrical properties of KTa(1-x)NbxO3 (KTN) ferroelectric materials, a KTN thin film was deposited on different substrates to investigate how KTN growth affects the microwave behavior. Interdigital capacitors and stubs were made on these films through a simple engraving process. Microwave measurements under a static electric field showed the importance of the substrate on the circuit behavior and, notably, on the tuning factor.
