| Summary: | 碩士 === 國立交通大學 === 電子研究所 === 84 === The dielectric behaviour with applied DC bias of Y-doped Ba1-
xSrxTiO3Ceramic and Ba1-xSrxTiO3/Silicon rubber has been
analyzed in the theme. Doping Y into Ba1-xSrxTiO3 ceramic
results in an improvement of dielectric constant change
percentage with applied DC bias. Thedielectric tunability which
is defined as the change percentage of thedielectric constant
for Ba1-xSrxTiO3 ceramic with applied DC bias in theparaelectric
state. Selecting of 0.1% Y-dopant concentration enhance the
dielectric tunability. Specific Sr/Ba molar fraction decides
the CurieTemperature. A composite mixing Ba0.8Sr0.2TiO3 powder
with different amount of silicon rubber polymer was fabricated.
Studying the dielectric behaviourof this elastic composite, a
tremendous reduction of dielectric constantsuggests that these
two phases are mixed in series connectivity. Theother case of
parallel connectivity is also fabricated by corresponding
thepolymer around the bulk sample. In this case, the dielectric
tunability isenhanced comparing to that of series case.
