论文摘要
从理论上讲，在2D半导体中流体动力和弹道方案之间的过渡，我们表明，高型2D GAA中的电子是迄今为止直接观察集体流体动力效应的最佳系统，即使在散装特性中独立于狭窄的系统中的复杂运输特征和小型系统中的较小系统和小型系统中，gurzhi feenomena是典型地进行了实验的实验。我们预测，在批量2D GAAS系统中，强烈的流体动力学引起的通用违反了对Wiedeman-Franz法律的易于范围，其适度为$ 10^6 \ Mathrm {cm}^2/vs $和密度$ 1 $ 1 $ -5 \ $ 5 \ times10^{11}}}}}}} \ mathrm} $ {cm} $ a $ ntody of pocy of to = $ t $ to $ to $ to $ to $ to = $ t = $ 2}
Considering theoretically the transition between hydrodynamic and ballistic regimes in 2D semiconductors, we show that electrons in high-mobility 2D GaAs are by far the best system for the direct observation of collective hydrodynamic effects even in bulk transport properties independent of complicated transport features in narrow constrictions and small systems where Gurzhi phenomena are typically studied experimentally. We predict a strong hydrodynamics-induced generic violation of the Wiedeman-Franz law in bulk 2D GaAs systems for mobilities as modest as $10^6 \mathrm{cm}^2/Vs$ and densities $1$-$5\times10^{11} \mathrm{cm}^{-2}$ in the temperature range of $T=1$-$40K$.
