We report an experimental observation and direct control of quantum transport that is mainly governed by the quantum chaotic dynamics of carrier motion in artificial two-dimensional Au lattices.Given the technologies of low-temperature deposition and newly developed double-probe scanning tunneling spectroscopy,carrier transport is constrained to two-dimensional propagation and subjected to the strong modulation of an in-plane structure.In well-ordered Au lattices,the band-like transport behavior manifesting as a wide gap with an anisotropic distribution is observed.Furthermore controlled structural modification performed by constructing coupled “stadiums” enables a transition of system dynamics in the lattices,which in turn establishes tunable resonant transport throughout a wide energy range.Our findings open the possibility of the construction and transport engineering of artificial lattices,which are governed by the geometrical arrangement of scatterers and quantum chaotic dynamics.

原子层厚度的二维原子晶体具有丰富的新奇物理特性，近年来引起了学术界的广泛研究。与块体材料相比，由于二维原子晶体材料的厚度只有单个或少个原子层厚度，因此其表界面物性对材料整体物性，如化学稳定性、电子结构等，起着至关重要的作用[1]。特别是具有不同性质的二维原子晶体构造的垂直异质结更是二维原子晶体物性研究与器件应用中的核心，然而在纳米尺度上对其界面的电学、力学以及热学等物理性质的研究缺乏有效的研究工具
