Black Phosphorus

Black Phosphorus (BP) is one of the allotropes of phosphorus, characterized by a layered structure and classified as a quasi-two-dimensional (2D) semiconductor material. In recent years, it has gained significant attention as a next-generation material in various fields, including energy storage, optoelectronic devices, biosensors, and catalysis.

Key Features

Electrical Properties: Semiconductor behavior with high carrier mobility (~1000 cm²/V·s or higher)

Tunable Bandgap: Bandgap can be adjusted based on thickness (number of layers) → advantageous for optoelectronic applications

Optical Anisotropy: Absorption and reflection spectra vary depending on the crystal axis direction
