Black phosphorus (BP), a van der Waals (vdW) layered material, has been intensively studied in recent years since the rediscovery of its thin-film form in 2014. It is considered as a promising material for mid-infrared (MIR) photodetection, due to its intrinsic narrow bandgap, tunable band properties, decent optical absorption, high room-temperature mobility, and high compatibility with silicon-based technology. Here, the recent advances in the synthesis techniques, the novel optoelectronic properties, and applications of thin-film BP flake in MIR photodetection are reviewed. Over 17 synthesis techniques of BP films, as well as their merits and drawbacks, are summarized and discussed. The recently discovered strain-, electric-field-, and chemical-doping-induced bandgap tuning effects in BP effectively extend its optical absorption cutoff wavelength into regime with longer wavelength (>4 mu m). In addition, the establishment of BP-based vdW heterostructures paves a new way to design novel high-performance MIR photodetectors. BP MIR photodetectors enabled by various photocurrent generation mechanisms (photoconductive, photogating, and photovoltaic effect) and device configurations (transistor-type, waveguide-coupled, Schottky-junction-type, and heterojunction-type devices) are summarized and compared.
