We have studied microwave response of a high-mobility two-dimensional electron system (2DES) contacted by two side electrodes. Using kinetic inductance of the 2DES and inter-electrode capacitance, we have constructed a subwavelength 2D plasmonic resonator. We have shown that the resonant frequency of this circuit can be controlled by 2D electron density, external magnetic field, or size of the electrodes. This opens up possibilities for using arrays of plasmonic circuits as tunable components in different frequency ranges.

使用动态二维电感和贴片电容的可调谐等离子体谐振器

我们研究了由两侧电极接触的高迁移率二维电子系统 (2DES) 的微波响应。利用 2DES 的动感电感和电极间电容，我们构建了一个亚波长 2D 等离子体谐振器。我们已经证明，该电路的谐振频率可以通过 2D 电子密度、外部磁场或电极尺寸来控制。这开辟了使用等离子体电路阵列作为不同频率范围内的可调组件的可能性。
