Phosphor Arsenic alloy is a semiconductor. We have different types of P-As alloys available containing a different ratio P/As. For low amounts of As the crystal can still be cleaved as a 2D crystal and the unit cell parameters are similar to black phosphorus. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers.

The P-As crystals produced at HQ Graphene have a typical lateral size of ~0.1 cm and have a metallic appearance.
