Black Phosphorus

Black Phosphorus Black phosphorus is a semiconductor with a band gap of ~0.3 eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers down to single layer phosphorus (phosphorene). We have also succeeded in the growth of an Phosphorus-Arsenic alloy which has a similar unit cell with the black phosphorus. For more information you can visit the product page of the Phosphorus-Arsenic alloy (click here). To buy black phosphorus crystals please click here.

The black phosphorus crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm and have a metallic appearance. Due to the large flat surface the crystals are ideal for optical (ARPES) and scanning probe microscopy (STM, AFM, ...) measurements. A selection of peer review publications on the black phosphorus we sell can be found below.
