This product is a high-purity black phosphorus crystal (≥99.5%), developed for fundamental research in low-dimensional and two-dimensional materials. Prepared via the chemical vapor transport method, it exhibits a well-defined layered crystal structure characteristic of black phosphorus, as confirmed by structural and morphological characterization. With its narrow bandgap and anisotropic electronic properties, this material is commonly employed in studies of field-effect transistors, photodetectors, and energy storage systems. The crystal is supplied in sealed packaging with a range of mass options to accommodate different experimental scales, from milligram to gram quantities. This material is particularly relevant for researchers investigating the tunable electronic and optoelectronic behavior of two-dimensional semiconductors.
