Two-dimensional (2D) materials are an emerging class of quantum materials providing a rich playground to investigate quantum and nanoscale processes and exploit them in innovative devices. The integration of these materials in scalable electronic, optoelectronic, and photovoltaic devices is still hindered by one or more of the following major limitations: (i) the absence of semiconducting bandgap; (ii) the inherent instability and degradation in ambient air; and (iii) the limited scalability due to the lack of large area synthesis processes. With this perspective, this project will focus on establishing a novel family of monoelemental 2D materials aiming at circumventing these limitations in order to harness quantum confinement properties in scalable devices involving integration processes compatible with the current semiconductor technology. The core strategy here is to establish group V 2D materials: Antimonene (2D antimony) and arsenene (2D arsenic) heterostructures and devices. Unlike the current 2D materials, group V 2D materials are highly stable and exhibit a tunable bandgap in the 0.36 to 2.62 eV range (blue to mid-infrared wavelength) in addition to graphene-like 2D confinement properties. Within the framework of this project, these properties will be thoroughly investigated and exploited to design and implement innovative, cost-effective mid-infrared light emitting devices operating in the 3-5 µm wavelength. To tackle this exciting research, the multidisciplinary team will develop and utilize theoretical approaches and experimental equipment that have never been combined heretofore. This world-class collaborative research has a strong potential to generate new scientific and technological knowledge that will contribute to shape the future of the emerging 2D materials and devices. **

二维（2D）材料是一类新兴的量子材料，为研究量子和纳米级过程并在创新设备中利用它们提供了丰富的平台。这些材料在可扩展的电子、光电和光伏器件中的集成仍然受到以下主要限制中的一个或多个的阻碍：（i）不存在半导体带隙;（ii）固有的不稳定性和在环境空气中的降解;以及（iii）由于缺乏大面积合成工艺而导致的有限的可扩展性。从这个角度来看，该项目将专注于建立一个新的单元素2D材料家族，旨在规避这些限制，以利用可扩展器件中的量子限制特性，这些器件涉及与当前半导体技术兼容的集成工艺。这里的核心战略是建立V族2D材料：锑烯（2D锑）和砷烯（2D砷）异质结构和器件。与目前的2D材料不同，V族2D材料是高度稳定的，并且除了石墨烯类2D限制特性之外，还表现出在0.36至2.62 eV范围（蓝色至中红外波长）内的可调谐带隙。在该项目的框架内，这些特性将被彻底研究和利用，以设计和实现在3-5 μm波长下工作的创新的、具有成本效益的中红外发光器件。为了解决这一令人兴奋的研究，多学科团队将开发和利用迄今为止从未结合过的理论方法和实验设备。这项世界级的合作研究具有产生新的科学和技术知识的强大潜力，这些知识将有助于塑造新兴2D材料和设备的未来。**
