High-Purity, Graphene-like 2D Material for Advanced Research and Innovation
As part of Alfa Chemistry's graphene-like materials portfolio, black phosphorus powder offers researchers a next-generation two-dimensional material with exceptional electronic and optical properties. Produced via chemical vapor transport (CVT) under precisely controlled conditions, this high-purity material is ideal for applications in nanoelectronics, optoelectronics, energy conversion, and environmental science
Product Overview
Black phosphorus is a thermodynamically stable allotrope of phosphorus with a layered, graphene-like crystal structure. Its key advantage lies in a tunable direct bandgap—ranging from 0.3 to 2.0 eV—in contrast to graphene, which lacks a bandgap. This distinctive feature enables its use in semiconductor devices, photonic systems, and biomedical technologies. As an emerging member of the 2D materials family, black phosphorus combines high carrier mobility, near-infrared (NIR) responsiveness, and good biocompatibility.
Key Features
- Thermodynamic Stability: Less reactive than white and red phosphorus; does not spontaneously ignite in air
- Adjustable Bandgap: Ranges from 0.3 to 2.0 eV, enabling applications in diverse semiconductor technologies
- Near-Infrared Absorption: Ideal for lasers, photodetectors, and optical sensors
- Layered Morphology: Facilitates exfoliation into monolayer phosphorene
- Paramagnetic Behavior: Magnetized under external magnetic fields without retaining permanent magnetism
- Low Shear Strength: Suitable as a solid-state lubricant in precision systems
