摘要:

对用于无数应用的复杂、自驱动、紧凑、超快、高性价比和宽带光传感器的空前需求激发了大量研究,在过去十年中促成了大量研究。除了光传感器中有源元件的光敏能力外,器件架构在光生载流子的产生和分离方面也至关重要。自石墨烯问世以及随后原子级薄二维材料的研究增长以来,研究人员开发并改造了不同家族的二维材料和器件架构,包括单元素二维、0D/2D、2D/2D、1D/2D堆叠结构等。本综述讨论了各种二维材料及其异质结构的光敏特性以及适用于紫外-近红外(UV-NIR)、短波红外(SWIR)、中波红外(MWIR)、长波红外(LWIR)和太赫兹(THz)光谱范围的特性的最新报告。它重点介绍了这一新兴领域的新颖性、在工程与材料科学边界处日益活跃的研究,特别是在载流子的产生、分离和提取方面,以及通过现代实验方法对基础科学理解的加深。严格考察了基于热释光电子效应(PPE)和局域表面等离子体共振(LSPR)效应同时作用、光热电效应(PTE)辅助的光电探测器(PDs)、波导集成的硅-二维PDs、金属-二维-金属PDs和有机材料PDs的器件。还简要讨论了利用各种计算方法研究用于光电探测的二维材料和异质结构的理论处理。

英文摘要:

The unprecedented demand for sophisticated, self-powered, compact, ultrafast, cost-effective, and broadband light sensors for a myriad of applications has spurred a lot of research, precipitating in a slew of studies over the last decade. Apart from the photosensing ability of an active element in the light sensor, the device architecture is crucial in terms of photoinduced charge carrier generation and separation. Since the inception of graphene and the subsequent research growth in the atomically thin 2D materials, researchers have developed and adapted different families of 2D materials and device architectures, including single element 2D, 0D/2D, 2D/2D, 1D/ 2D stacked structures, and so on. This review discusses the recent reports on the light-sensing properties of various 2D materials, their heterostructures, and characteristics applicable to the ultraviolet-near infrared (UV-NIR), short-wave IR (SWIR), mid-wave IR (MWIR), long-wave IR (LWIR), and terahertz (THz) spectral ranges. It highlights the novelty of the burgeoning field, the heightened activity at the boundaries of engineering and materials science, particularly in the generation of charge carriers, their separation, and extraction, and the increased understanding of the underpinning science through modern experimental approaches. Devices based on the simultaneous effects of the pyro-phototronic effect (PPE) and the localized surface plasmon resonance (LSPR) effect, the photothermoelectric effect (PTE)-assisted photodetectors (PDs), waveguide-integrated silicon-2D PDs, metal-2D-metal PDs, and organic material PDs are examined rigorously. Theoretical treatment utilizing various computational approaches to investigate 2D materials and heterostructures for photodetection applications is also briefly discussed.
