Abstract

Abstract : The serendipitous chemical and physical properties of 2D materials (2DMs) have provoked enormous research efforts. These materials suggest an attractive podium for various optoelectronic, energy conversion, energy storage, and sensing device applications. The outstanding optical and electrical properties combined with superior mechanical characteristics make 2DMs an unprecedented choice for the diversity of advanced high‐efficient photodetectors. The functionalities and properties of such materials can further be tailored by combining 2DMs in the form of nanoarchitecture heterostructures. Thus, this study focuses on the recent advancements of 2D heterostructures for highly efficient photodetectors started with an introduction to their basic structural configurations. Then, a discussion on their state‐of‐the‐art synthesis methods is stressing the approaches that contrive the current margins and provide a path toward realizing these materials for efficient photodetector applications. The advanced characterization techniques that are useful for analyzing 2DM‐based photodetectors and underlying mechanisms for superior device performance are summarized systematically. Furthermore, utilization of 2DM‐based heterostructures for high‐performance photodetector applications with the special emphasis on different photodetection mechanisms is also discussed comprehensively at the end. Abstract : The functionalities and properties of 2D materials can further be modified by their combination in the form of heterostructures to achieve high‐performance devices. This aims to highlight the role of graphene and beyond graphene heterostructures to achieve highly efficient photodetectors with a special emphasis on different photodetection mechanisms.
