论文摘要
我们通过在GAAS/AlgaAS异质结构中的高弹性二维电子系统上，通过非局部电阻测量和高分辨率动力学模拟研究流体动力和弹道传输方案。我们在这两个政权中都存在集体运输现象的存在，并证明了负面的非局部抵抗力和当前涡度并不仅仅是流体动力学制度的独有性。合并的实验和模拟突出了设备设计，测量方案以及实验设备的一对一建模的重要性，以划定各种运输方式。
We study hydrodynamic and ballistic transport regimes through nonlocal resistance measurements and high-resolution kinetic simulations in a mesoscopic structure on a high-mobility two-dimensional electron system in a GaAs/AlGaAs heterostructure. We evince the existence of collective transport phenomena in both regimes and demonstrate that negative nonlocal resistances and current vortices are not exclusive to only the hydrodynamic regime. The combined experiments and simulations highlight the importance of device design, measurement schemes and one-to-one modeling of experimental devices to demarcate various transport regimes.
