We have investigated the spectrum of two-dimensional (2D) plasmon polaritons over the full range of magnetic fields. In our study, we investigate a disk-shaped two-dimensional electron system (2DES) with a metallic gate on the backside of the substrate. Importantly, we show that 2D plasmon polaritons hybridize with the ${\mathrm{TM}}_0$ photonic mode of a dielectric waveguide formed by a sample substrate. We have developed a theory for plasmon-polaritons in an infinite 2DES. We find the experimental data to be in good agreement with the developed theory.

二维等离子体激元的磁色散

我们已经研究了整个磁场范围内的二维 (2D) 等离子体激元的光谱。在我们的研究中，我们研究了在基板背面具有金属栅极的盘形二维电子系统 (2DES)。重要的是，我们表明 2D 等离子体激元与${\mathrm{TM值}}_0$由样品衬底形成的介质波导的光子模式。我们已经开发了一个无限 2DES 中的等离子体激元理论。我们发现实验数据与发展的理论非常吻合。
