AI总结:

本研究制备用于太赫兹全介质超材料的高介电常数SrTiO3,对比三种烧结工艺后发现放电等离子烧结可制备出介电常数与单晶相当的高密度陶瓷,为太赫兹超材料制备提供了有效方案。

摘要:

本研究制备了用于实现工作在太赫兹频率的全介质超材料的高介电常数钛酸锶(SrTiO3)。通过对比不同制备工艺发现,放电等离子烧结(Spark Plasma Sintering)是制备具有高介电常数的高密度陶瓷的最有效烧结工艺。我们将该烧结工艺与另外两种工艺进行了对比。对制备的样品在低频和太赫兹频段进行了表征,并将其相对介电常数与参考SrTiO3单晶的介电常数进行了比较。结果显示,采用放电等离子烧结制备的样品的介电常数与单晶的介电常数相当。

英文摘要:

High permittivity SrTiO3 for the realization of all-dielectric metamaterials operating at terahertz frequencies was fabricated. A comparison of different processing routes evidences that Spark Plasma Sintering is the most effective sintering process to yield high density ceramic with high permittivity. We compare this sintering process with two others. The elaborated samples are characterized in the low frequency and in the terahertz frequency ranges. Their relative permittivities are compared with that a reference \sto single crystal. The permittivity of the sample elaborated by Spark Plasma Sintering is as high as that the single crystal.
