Black phosphorus (BP) is being explored as an alternative semiconductor material to silicon and graphene due to its high carrier mobility, tunable bandgap, and potential for applications in flexible electronics and internet of things devices. BP has shown carrier mobilities over 10,000 cm2/V∙s, higher than silicon, as well as a bandgap that can be tuned by controlling the number of layers. While challenges remain around scalable production and material stability, BP shows promise as a competitor to silicon and ability to overcome limitations of graphene for semiconductor applications.
