The influence of doping, electric field cycling, and annealing temperature on tuning characteristics (tunability) was analyzed and an optimized bias region for the maximum tunability was defined. Additional focus was made on an antiferroelectric-like (AFE) behavior, which occurs for &amp;gt; 50% Zr doping. The presence of both the ferroelectric and the AFE phase manifests itself in specific&amp;nbsp;C&amp;nbsp;–&amp;nbsp;V&amp;nbsp;behavior, where a reduced bias range is required for tuning, however, at the cost of a smaller tunability. The suitability of this behavior for varactor applications is also discussed.</style></abstract><issue><style face="normal" font="default" size="100%">10</style></issue></record></records></xml>
