Black Phosphorus Crystals

Black Phosphorus Crystals

Black Phosphorus (BP) is a layered semiconductor with a puckered orthorhombic structure, exhibiting strong anisotropic electronic, optical, and thermal properties. Its direct bandgap, which is variable from ~0.3 eV (bulk) to ~2.0 eV (monolayer), makes it a highly applicable material for applications in optoelectronics, photonics, energy storage, and 2D materials research. Our Black Phosphorus crystals are synthesized using the Chemical Vapor Transport (CVT) method, with high purity, precise stoichiometry, and high crystallinity.
