Emerging black phosphorus analogue nanomaterials for high-performance device applications

In recent years, layered black phosphorus (BP) nanostructures have demonstrated great potential applications in transistors, optoelectronics and logic devices due to their excellent intrinsic electronic and optoelectronic properties. However, the high cost of BP and its rapid degradation upon exposure to ambient conditions turn out to be the two critical bottlenecks hampering practical applications. With the development of semiconductors in leaps and bounds, a new wave of exploration of black phosphorus analogues (BPAs), whose excellent optoelectronic performance and high chemical stability under ambient conditions unveil great promise for practical applications, has emerged. This review presents the synthesis and morphology control of emerging BPAs, the latest progress in understanding the fundamental properties of BPA nanostructures, and the recent advances in constructing prototypical high-performance BPA-based devices for practical applications. Finally, the prospects for future research, application opportunities, and the accompanying challenges of BPAs are discussed.
