论文摘要
我们通过应用平面单轴菌株在调制掺杂的Alas量子井中调整了二维（2D）等离子体谱。我们表明，等离子体频谱的戏剧性变化是由于应变引起的各向异性$ x_x $和$ x_y $ valleys之间的电荷载体重新分布而引起的。发现的压电效应提供了一种研究2D系统的频带结构的工具。我们使用压电质效应来测量valley的能量分裂如何取决于变形。该依赖关系产生$ e_2 =（5.6 \ pm 0.3）$ 〜ev的Alas变形电位。
We demonstrate tuning of two-dimensional (2D) plasmon spectrum in modulation-doped AlAs quantum wells via the application of in-plane uniaxial strain. We show that dramatic change in the plasma spectrum is caused by strain-induced redistribution of charge carriers between anisotropic $X_x$ and $X_y$ valleys. Discovered piezoplasmonic effect provides a tool to study the band structure of 2D systems. We use piezoplasmonic effect to measure how the inter-valley energy splitting depends on the deformation. This dependency yields the AlAs deformation potential of $E_2 = (5.6 \pm 0.3)$~eV.
