二维(2D)材料合成和组装的最新进展为原子薄层膜的各种应用奠定了基础。这些2D材料具有丰富而多样的特性,例如层依赖性的带隙,有趣的自由度自由度和可变的晶体结构。它们在微纳米设备中显示出广泛的应用前景。同时,具有升高电压,高迁移率和高温导电率的宽带隙半导体(WBS)显示了在高频微波设备,高温和高功率电子设备中的重要应用。除了对单个2D材料或WBS材料的研究外,多功能2D/WBS异质结构还可以在界面促进载流子运输,从而有可能提供新颖的物理现象和应用,并提高电子和光电设备的性能。在这篇综述中,我们概述了2D材料和WBS材料的异质结构的优势,并介绍了2D/WBS异质结构的构建方法。然后,我们介绍了2D/WBS异质结构的应用中的多样性和最新进展,包括光电探测器,光催化,传感器和与能量相关的设备。最后,我们提出了2D/WBS异质结构的当前挑战,并提出了未来有前途的研究指示。
Recent progress in the synthesis and assembly of two-dimensional (2D) materials has laid the foundation for various applications of atomically thin layer films. These 2D materials possess rich and diverse properties such as layer-dependent band gaps, interesting spin degrees of freedom, and variable crystal structures. They exhibit broad application prospects in micro-nano devices. In the meantime, the wide bandgap semiconductors (WBS) with an elevated breakdown voltage, high mobility, and high thermal conductivity have shown important applications in high-frequency microwave devices, high-temperature and high-power electronic devices. Beyond the study on single 2D materials or WBS materials, the multi-functional 2D/WBS heterostructures can promote the carrier transport at the interface, potentially providing novel physical phenomena and applications, and improving the performance of electronic and optoelectronic devices. In this review, we overview the advantages of the heterostructures of 2D materials and WBS materials, and introduce the construction methods of 2D/WBS heterostructures. Then, we present the diversity and recent progress in the applications of 2D/WBS heterostructures, including photodetectors, photocatalysis, sensors, and energy related devices. Finally, we put forward the current challenges of 2D/WBS heterostructures and propose the promising research directions in the future.
