MSE PRO Black Phosphorus-Arsenic (b-AsP) 2D Crystal, 0.2g

The two dimensional layered inorganic materials have gained significant attentions recently owing to their thickness dependent on physical and chemical properties. Similar to graphene, black phosphorus and black arsenic have a two-dimensional layered structure consisting of individual layers stacked together through weak van der Waals forces. They have unique properties, such as high carrier mobility, strong infrared responsivity, widely tunable bandgap, in-plane anisotropy, spontaneous electric polarization and good bio-compatibility. Recent research found out that combining these materials at high pressure can get Black Phosphorus-Arsenic (b-AsP), which will improve their various characteristics. It is widely used for field-effect transistors, optical devices, catalysis, bio-sensor, semiconductor, detectors and battery research.
