Low-dimensional superconductors have been at the forefront of physics research due to their rich physical properties such as high-temperature (Tc) superconductivity. In this article, we review the field of emergent high-Tc superconductivity at interfaces of heterostructures, focusing on the experimental advances and its physical mechanism. Charge transfer between constituent materials leads to two-dimensional carrier confinement that facilitates occurrence of superconductivity at the interface. We discuss the similarities between bulk high-Tc superconductors and interface systems, as well as implications from a survey of interface superconductors. We expect that the hybrid heterostructures and the ability to manipulate them on an atomic scale could be an enormously fertile ground to explore superconductivity with higher critical temperature Tc.

低维超导体由于其丰富的物理特性（例如高温（T c）超导性）而一直处于物理学研究的前沿。在本文中，我们回顾了异质结构界面处新兴的高T c超导性领域，重点是实验进展及其物理机理。组成材料之间的电荷转移导致二维载流子限制，这有助于在界面处发生超导。我们讨论了散装高T c之间的相似之处超导体和接口系统，以及对接口超导体的调查得出的结论。我们预计，杂化异质结构及其在原子尺度上进行操作的能力可能是探索具有更高临界温度T c的超导性的巨大沃土。
