Recent advances in low-dimensional semiconductor nanomaterials and their applications in high-performance photodetectors

Low-dimensional (including two-dimensional [2D], one-dimensional [1D], and zero-dimensional [0D]) semiconductor materials have great potential in electronic/optoelectronic applications due to their unique structure and characteristics. Many 2D (such as transition metal dichalcogenides and black phosphorus) and 1D (such as NWs) materials have demonstrated superior performance in field effect transistors, photodetectors (PDs), and some flexible devices. And in some hybrid structures of 0D materials and 1D or 2D materials, the modification of 1D and 2D devices by 0D materials is embodied. This type of hybrid heterostructure has a larger performance optimization compared with the original. In the application of PDs, the variety of low-dimensional materials and properties enable wide-spectrum detection from ultraviolet UV to infrared, which provide a potential option for PDs under various conditions. For flexible electronic devices, high performance and mechanical stability are two important features. Low-dimensional materials offer unparalleled advantages in flexible devices. In this review, we will focus on the various low-dimensional materials that have been extensively studied and their applications in the electronics/optoelectronic and flexible electronics. From the composition and lattice structure of materials (including alloys) to the construction of various devices and heterostructures, we will introduce their application and recent development under various conditions. These works can provide valuable guidance for the construction and application of more high-performance and multifunctional devices. image
