Abstract
Uniform ZrO2 nanoballs were synthesized at 700℃ using the inverse replication method through a colloid-imprinted carbon (CIC) template. The structural, dielectric, and conducting properties of the ZrO2 nanoballs were investigated and compared with those of ZrO2 film prepared by sol-gel method and powdered ZrO2 chemical. Both the monoclinic and cubic phases were found in the ZrO2 balls and film but the ZrO2 chemical showed a monoclinic phase, where the cubic structure is known to be formed at above 2,300℃. ZrO2 nanoballs showed the lower dielectric property of k = 21.2 at 1 MHz because the 8-coordinated cubic phase in the ZrO2 nanoball produced lower polarization than the polarization of the 7-coordinated monoclinic ZrO2 chemical (k = 23.6). The dielectric stability was maintained in each ZrO2 ball, film, and chemical under the applied forward and reverse voltage range (−5 to +5 V) at 1 MHz. The ionic conductivities were 7.86 × 10−8/Ω·cm for ZrO2 nanoballs, 3.29 × 10−8/Ω·cm for ZrO2 chemical, and 6.70 × 10−5/Ω·cm for the thickness of 1,053 nm ZrO2 film at room temperature with the electronic contribution being less than 0.006%.
