Compounds with heterolayered architecture, as a family of two-dimensional (2D) materials, are composed of alternating positive and negative layers. Their physical properties are determined not only by the charged constituents, but also by the interaction between the two layers. This kind of material has been widely used for superconductivity, thermoelectricity, energy storage, etc. In recent years, heterolayered compounds have been found as an encouraging choice for infrared photodetectors with high sensitivity, fast response, and remarkable reliability. In this review, we summarize the research progress of heterolayered materials for infrared photodetectors. A simple development history of the materials with three-dimensional (3D) or 2D structures, which are suitable for infrared photodetectors, is introduced firstly. Then, we compare the differences between van der Waals layered 2D materials and heterolayered 2D cousins and explain the advantages of heterolayered 2D compounds. Finally, we present our perspective on the future direction of heterolayered 2D materials as an emerging class of materials for infrared photodetectors.

用于红外光电探测器的异质层结构二维化合物


具有异质层结构的化合物是二维 (2D) 材料家族，由交替的正负层组成。它们的物理性质不仅取决于带电成分，还取决于两层之间的相互作用。这种材料已广泛应用于超导、热电、储能等领域。近年来，异质层化合物已被发现是高灵敏度、快速响应和卓越可靠性的红外光电探测器的令人鼓舞的选择。本文综述了红外光电探测器异质层材料的研究进展。首先简单介绍了适用于红外光电探测器的三维（3D）或2D结构材料的发展历史。然后，我们比较了范德华层状二维材料和异质层二维材料之间的差异，并解释了异质层二维化合物的优点。最后，我们提出了对异质层二维材料作为红外光电探测器新兴材料的未来方向的看法。
