本文报道了在r（s）= 19-39范围内对稀双层二维空穴系统的阻力测量结果。我们观察到一个强大的增强阻力的库仑相互作用的简单玻尔兹曼计算，并偏离T2的依赖，不能解释的声子介导的，等离子体增强，或无序相关的过程。我们认为，这种偏离的结果从相互作用的影响，在稀释制度。
We report drag measurements on dilute double layer two-dimensional hole systems in the regime of r(s) = 19-39. We observed a strong enhancement of the drag over the simple Boltzmann calculations of Coulomb interaction, and deviations from the T2 dependence which cannot be explained by phonon-mediated, plasmon-enhanced, or disorder-related processes. We suggest that this deviation results from interaction effects in the dilute regime.
