Black phosphorus, on the other hand, has a widely-tunable band gap that varies depending on how many layers are stacked together. This means that black phosphorus can be tuned to absorb light in ...

It's more efficient in its natural state than black phosphorus but it's difficult to open its band gap; therefore we tuned BP's band gap to resemble the natural state of graphene, a unique state ...

Ultrathin black phosphorus is a two-dimensional semiconductor with a sizeable band gap. Its excellent electronic properties make it attractive for applications in transistor, logic and ...

Up until now, black phosphorus, also known as phosphorene ... is that phosphorene has a natural band gap. This means that phosphorene doesn't conduct electricity at every energy state.

"So far, researchers have mainly used bulk black phosphorus to exfoliate atomically thin layers," says Oliver Rader, an author of the study. "These also show a large semiconducting band gap but do ...

"In this context, we report the modulation of a unique room-temperature NDR effect with high peak current in ambipolar black phosphorus (BP) transistors, which is induced by lateral carrier density ...
