The impact of electrical stressing on the microwave performance of the SrTiO3 films deposited onto different substrates (MgO and LaAlO3) by pulsed laser deposition has been investigated. The most important characteristics of the tunable microwave component ...
A strong de electric field dependence of the dielectric permittivity makes perovskite ferroelectrics promising materials for tunable microwave devices like phase shifters, tunable resonators, tunable filters etc. Dielectric loss is a crucial parameter for ...
Novel design of an integrated digital refelction-type phase shifter based on a Barium Strontium Titanate thin-film capacitor is presented. Measured characteristics of the phase shifter am compared with the theoretically predicted ones. ...
Structural investigations of SrTiO3 thin films deposited by pulsed laser ablation onto MgO and LaAlO3 substrates are presented. The residual strain along the c -axis (the growth direction) was evaluated with conventional X-ray diffraction. Evaluation of th ...
