Helmholtz-Zentrum Berlin für Materialien und Energie. (2018, October 15). Blue phosphorus mapped and measured for the first time. ScienceDaily Citat: "...The element phosphorus can exist in various allotropes and changes its properties with each new form. So far, red, violet, white and black phosphorus have been known...USA, performed model calculations to predict that "blue phosphorus" should be also stable. In this form, the phosphorus atoms arrange in a honeycomb structure similar to graphene, however, not completely flat but regularly "buckled."...semiconductor with a rather large band gap of 2 electron volts. This large gap, which is seven times larger than in bulk black phosphorus...In 2016, blue phosphorus was successfully stabilized on a gold substrate by evaporation. Nevertheless, only now we know for certain that the resulting material is indeed blue phosphorus..."
