摘要

The Pt/(Ba_0.7Sr_0.3)TiO₃ (BST)/YBa ₂Cu₃O_7-x capacitors were prepared and investigated for the dead-layer (DL) dielectric constant (ε_d) and the DL thickness (t_d). Through the measurements of the current-voltage characteristics, the t_d×ε_d were obtained. The DL thickness and the dielectric constant in the interface of Pt/BST were quantitatively determined to be 2.8 nm and 42.6, respectively, based on series capacitor model and leakage behavior analysis. It was shown that a dielectric constant of the bulk BST ferroelectric layer of 1370 was obtained.
