Black Phosphorus Crystal
CAS No.: 7723-14-0
Two-dimensional black phosphorous, also known as phosphorene, is one of ten allotropes of phosphorous. This material is a new entrant into the field of advanced 2-D materials and shares many of the same properties as others in the same class, such as graphene.
Much of the excitement surrounding black phosphorous stems from its tunable band gap, a critical characteristic missing from graphene. Scientists have been successful in fine-tuning the band gap of black phosphorous in a range from 0.3 to 2.0 electron volts, a wider range than any other 2-D material currently being studied. The band gap also opens possibilities in photonics, since light absorption, emission, and modulation abilities are dependent upon the size of the band gap. Black phosphorus’s wide band gap range allows it to absorb and emit light with wavelengths from 0.6 to 4.0 micrometers, both visible and infrared.
ACS Material is proud to be at the forefront of research into 2-D materials by providing high-quality black phosphorous crystal to leading innovators around the world.
