Recent advances in enhancing the photodetector performance of 2D materials by combining them with organic thin films

Abstract

Two dimension (2D) material-based photodetectors usually indicate excellent properties such as ultrafast and broadband response, but the atomic thickness of 2D materials usually leads to low absorption coefficient. Pure 2D material-based photodetectors also suffer from serious drawbacks such as short carrier lifetime, low optical absorption coefficient, and weak built-in field. Organic materials present excellent properties such as flexibility, high absorption coefficient, low cost and large area, which are very suitable for enhancing the detector performance of 2D materials. In this paper, the development of 2D material photodetectors by combining 2D materials with organic thin films since their proposal to date is reviewed. The 2D/organic photodetectors are classified into three categories (graphene-based, MoS2-based and others), and their development history and research status are comprehensively summarized and reviewed. Organic thin films are categorized into small molecule organic thin films, organic polymer thin films, complex organic thin films, and bilayer organic thin films, and the device performance of each type of material and the mechanism behind the high performance are discussed in detail. Finally, the future development of 2D/organic photodetectors is envisaged. The aim of this paper is to provide new research ideas and directions for 2D/organic heterojunction photodetectors with ultra-high performance and promote the application of these combined photodetectors.
