我们展示了工程的低太赫兹范围的二维电子系统的等离子体光谱通过修改它们的几何形状。具体来说,我们已经建模,制造和测量两个设备进行比较。第一装置具有矩形通道,而第二装置是梯形的,其被设计成通过引起装置宽度沿着等离子体传播方向的变化来支持更丰富的等离子体光谱。我们发现,虽然等离子体共振频率和场分布在矩形设备可以在很大程度上描述了一个简单的一维分析模型,在梯形设备中建模的场分布示出了一个更复杂的模式与显着的变化沿着的通道的长度,所以需要一个二维的治疗。结果表明,修改通道的几何形状,以获得不同的光谱在实验中的潜力,在设计新型太赫兹范围的设备,如等离子体激元的源和探测器的潜在应用。
We demonstrate engineering of the low-terahertz range plasmonic spectra of two-dimensional electron systems by modifying their geometry. Specifically, we have modelled, fabricated, and measured two devices for comparison. The first device has a rectangular channel, while the second is trapezoidal, designed to support a richer plasmonic spectrum by causing variation in the device width along the direction of plasmon propagation. We show that while plasmon resonant frequencies and field distributions in the rectangular device can largely be described by a simple one-dimensional analytical model, the field distributions modelled in the trapezoidal device shows a more complex pattern with significant variation along the length of the channel, so requiring a two-dimensional treatment. The results illustrate the potential of modifying the channel geometry to obtain different spectra in experiments, with potential applications in the design of novel terahertz-range devices, such as plasmon-based sources and detectors.
