摘要
二维材料异质结因其特有的层状结构和优异的光响应性质,被认为具有应用于新一代光探测器件的潜力。二维材料家族具有丰富的种类,因其能带带隙范围分布广,光电响应可覆盖从紫外到红外的波谱范围。另外二维材料层间通过范德瓦尔斯力相结合,因此理论上可以利用不同二维材料层间的范德瓦尔斯力相互作用制备出多种性能优异的二维材料异质结。近年来有多种二维材料异质结通过机械堆叠法及CVD生长法被制备出来,且二维材料异质结光探测器在可见光至远红外波段表现出优异的性质。在这样的研究背景之下,本文从二维材料异质结的制备、器件制备与器件性能等几个方面综述了近年来二维材料异质结光探测器的研究进展。
The two-dimensional(2D)heterostructures are considered to have the potential to be applied to a new generation of photodetectors due to its unique two-dimensional layered structure and excellent photoresponse properties.The 2D material family is rich in variety,because of its wide band gap distribution,the photoresponse can cover the range from ultraviolet to infrared.Since the two-dimensional material layers are combined by van der Waals force,theoretically,it is possible to use the van der Waals force interaction between different two-dimensional material layers to prepare a variety of 2D heterostructures with excellent performance.In recent years,a variety of 2D heterostructures have been fabricated by mechanical stacking and CVD growth methods,and the 2D heterostructures photodetectors show excellent performance in the visible to far-infrared band.According to this research background,this paper reviews the research progress on 2D heterostructure photodetectors in recent years from the aspects of preparation of 2D heterostructures,the device preparation,and the device performance.
