论文摘要
当两个原子晶格之间形成相对于彼此的两个原子晶格之间形成时，Moiré模式可能会导致新的电子行为。然而，固体不仅是原子晶格的特征，而且还具有不需要与晶格相称的电荷或磁激发。这提出了一个问题，即是否可以通过结合定期电子调制和原子晶格来获得Moiré。在这里，我们报告发现一维电荷密度波（1D-CDW）是原子晶格和在隐藏顺序（HO）uru $ _2 $ _2 $ _2 $ si $ _2 $的带有电子散射的热点之间的moiré图案。 Moiré是通过在低温下将晶体骨折产生的。我们的结果表明，电荷互动是与HO竞争的最相关的功能之一。$ _2 $ si $ _2 $。
Moiré patterns can lead to fundamentally new electronic behavior when formed between two atomic lattices slightly shifted with respect to each other. A solid is however not just characterized by the atomic lattice, but also by charge or magnetic excitations that do not need to be commensurate to the lattice. This raises the question if one can obtain a moiré by combining periodic electronic modulations and the atomic lattice. Here we report on the discovery of a one-dimensional charge density wave (1D-CDW) which is a moiré pattern between the atomic lattice and a hot spot for electronic scattering in the bandstructure of the hidden order (HO) state of URu$_2$Si$_2$. The moiré is produced by fracturing the crystal at low temperatures. Our results suggest that charge interactions are among the most relevant features competing with HO in URu$_2$Si$_2$.
