The dielectric loss modes of SrTiO[sub 3] thin films deposited on different substrates are reported. Two dielectric loss modes around 165 and 75 K (at 10 kHz) with field-independent T[sub m] are emphasized. The physical origin of the dielectric modes is discussed and is tentatively attributed to the motion of oxygen vacancies. © 2002 American Institute of Physics.

    We present low-frequency dielectric loss and nonlinearity measurements in SrTiO[sub 3] thin films grown by pulsed laser deposition on SrRuO[sub 3] electrode layers. A low loss tangent in the order of 10[sup -4], close to the level found in SrTiO[sub 3] single crystals, was observed. Combined...

    Compositionally graded (Ba0.7Sr0.3)(SnxTi1-x)O3 (BSSnT) (x=0.1, 0.2, 0.3, and 0.4) thin films were prepared by pulse-laser deposition on (La0.7Sr0.3)CoO3/LaAlO3 substrates. A highly (100) oriented structure was obtained for both the upgraded (x increased from the bottom layer) and downgraded (x...

    In this study, the thickness dependence of tunability in Ti-doped K(Ta,Nb)O3 thin films is reported. The films were grown using pulsed laser deposition. Doping with Ti reduces losses via acceptor doping. Measurements of interdigitated electrode devices using K(Ta,Nb)O3 films of varying thickness...
