Abstract
Pulsed laser deposition (PLD) of YBa2Cu3O7-x (YBCO) thin films on both sides of 3-inch diameter sapphire wafers and LaAlO3 (LAG) cylinder su bstrates, respectively, is a basic and flexible technique in order to optimize microwave bandpass filters for wireless communication systems . The large-area and double-side PLD technique allows homogeneous and reproducible YBCO deposition on both substrate sides with inductively measured critical current densities j(c) of 3 x 10(6) to 5 x 10(6) A/c m(2) at 77 K with a YBCO thickness of 350 nm to 600 nm. Selected resul ts of compositional, structural, electrical, and microwave characteriz ation of the PLD-YBCO films are reported.
