Recently,black phosphorus (BP) has joined the two-dimensional material family as a promising candidate for electronic and photonic applications due to its moderate bandgap,high carrier mobility,and unusual in-plane anisotropy.Here,we review recent progress in BP-based devices,such as field-effect transistors,contact resistance,quantum transport,stability,photodetector,heterostructure,and in-plane anisotropy.We also give our perspectives on future BP research directions.
