Single crystals of black phosphorus (phosphorene or BP) for graphene-like exfoliation. Item includes one crystal with minimum dimensions of 5mm x 5mm or equivalent. Black phosphorus has been an intensively studied material in the field of two-dimensional crystals. Some recent publications for BP may be found on 2DResearch.
 
Manchester Nanomaterials offers single crystals of BP  with purity >99.99%. The Raman spectrum of black phosphorus shows three main peaks between 300 - 600 cm-1 as shown in the figure above, in agreement with literature values.
