论文摘要
由于与高$ T_C $ cuprates的关联，无限层镍盐中超导性的发现引起了很多关注。首先在散装样品中，随后在薄膜中证明了铜土超导性。然而，在镍盐中，情况已经逆转：尽管作为散装现象激增，但到目前为止，镍超导性只有在薄膜中报道。同时，无限层镍的细节产生了不同的界面和表面效应，这些界面和表面效应决定了它们的散装与薄膜行为。在本文中，我们提供了有关这些重要方面的概述。
The discovery of superconductivity in infinite-layer nickelates has attracted much attention due to their association to the high-$T_c$ cuprates. Cuprate superconductivity was first demonstrated in bulk samples and subsequently in thin films. In the nickelates, however, the situation has been reversed: although surging as a bulk phenomenon, nickelate superconductivity has only been reported in thin films so far. At the same time, the specifics of infinite-layer nickelates yield distinct interface and surface effects that determine their bulk vs thin-film behavior. In this paper, we provide an overview on these important aspects.
