  • Boron: a hunt for superhard polymorphs 
    Oganov, A.R.; Solozhenko, V.L. (Сверхтвердые материалы, 2009)
    Boron is a unique element, being the only element, all known polymorphs1 of which are superhard, and all of its crystal structures are distinct from any other element. The electron-deficient bonding in boron explains its ...
