How does phosphorene compare to graphene and other 2D materials?

Single-layer black phosphorus’ hole mobility compares favourably with Transition Metal Dichalcogenide Monolayers (TMDCs) but is orders of magnitude below that of graphene. Thermal conductivity is again below that of graphene, but competitive with TMDCs. Transistors fabricated from few-layer phosphorene display a high on/off ratio of 105 — significantly better than unmodified graphene, but falling behind TMDCs.

Phosphorene can be seen as an intermediary material, taking favourable properties of graphene and TDMCs but dispensing with their undesirable characteristics.

A comparison between some of the relevant optoelectronic properties of 2D materials is given in the table below.
