摘要

我们证明了利用电场调节钛酸锶薄膜介电常数的可能性。我们建议在这种薄膜上沉积一种金属超材料结构，设计成在太赫兹范围内共振。这个共振的振幅和频率可以通过施加偏置来调节。

Electric-field tunable THz metamaterials based on strained SrTiO3 films

We demonstrate the possibility to tune the permittivity of thin films of strontium titanate by means of an electric field. We propose to deposit on top of such films a metallic metamaterial structure designed to resonate in the terahertz range. The amplitude and frequency of this resonance will then be tunable by applying a bias.
