In the post-silicon era, two-dimensional (2D) layered semiconductors emerge as one of the most competitive materials for potential substitution of silicon in semiconductor technology. Among 2D semiconductors, black phosphorus (BP) is most studied, due to its high carrier mobility and desirable optical properties in mid-infrared region. First, the capacitance investigation of electronic properties of BP is introduced. And then, the transport properties of thin-film BP and its applications in FETs, radio-frequency transistors and logic inverters are presented. At last, the optical properties and efficient bandgap tuning properties in BP are discussed, based on which widely tunable mid-infrared photodetectors are demonstrated, with a photoresponse cutoff frequency up to 7.7 micrometer.
