Black arsenic-phosphorus (black AsP) crystals represent a cutting-edge 2D material that combines the structural advantages of black phosphorus with the greater tunability enabled by arsenic incorporation. With an adjustable bandgap ranging from 0.052 to 0.13 eV, black AsP is especially well-suited for broadband infrared detection and other advanced optoelectronic applications.
Product Overview
Engineered through precise control of the As/P atomic ratio, black AsP offers a flexible platform for tailoring electrical and optical properties to meet specific application needs. Its robust layered structure—held together by weak van der Waals forces—enables easy exfoliation down to monolayer thickness, facilitating integration into nanoscale devices. Compared to pure black phosphorus, black AsP demonstrates significantly improved environmental stability, making it more practical for real-world use.
