新型二维材料的出现激发了全世界光电子领域基础研究和应用技术的研究热情。在这里，我们全面概述了基于非层状2D材料（NL 2DM）的光电器件的最新进展，这是2D家族的新鲜血液。我们开始与实现非层状材料的二维几何的常用方法，包括货车德瓦尔斯外延，二维模板辅助拓扑转换，空间受限生长方法，自限生长方法，和热压方法的阐述。然后，我们提出了基于NL 2DM的光电探测器，将其分为原始金属-半导体-金属光电探测器和异质结光电探测器（HJPD）。接下来，我们总结了新型NL 2DM光电器件，包括偏振敏感光电探测器和柔性光电探测器。在此之后，我们介绍了提高的NL 2DM光电探测器的光敏性的策略，基于器件结构工程。随后，我们描述了基于NL 2DM的光伏器件。最后，我们强调了在这个快速发展的研究领域进一步发展所面临的关键挑战，沿着提出了解决这些问题的策略。
The emergence of novel 2D materials has stimulated worldwide research enthusiasm in both fundamental research and applied technologies in the realm of optoelectronics. Here, we provide a comprehensive overview on the recent advancements of photoelectric devices based on non-layered 2D materials (NL2DMs), fascinating fresh blood of the 2D family. We begin with an elaboration of the common approaches to implement 2D geometry of non-layered materials, including van der Waals epitaxy, 2D template assisted topotactic conversion, the space-confined growth method, the self-limited growth method, and the hot-pressing method. Then, we present photodetectors built on NL2DMs by dividing them into pristine metal–semiconductor–metal photodetectors and heterojunction photodetectors (HJPDs). Next, we summarize novel NL2DM optoelectronic devices, including polarization-sensitive photodetectors and flexible photodetectors. After this, we introduce strategies toward improving the photosensitivity of NL2DM photodetectors based on device structure engineering. Subsequently, we describe photovoltaic devices based on NL2DMs. Finally, we highlight the key challenges facing further development in this rapidly progressing research field, along with proposed strategies addressing these issues.
