Description:
Author(s): R. F. Zhang, Z. J. Lin, Y. S. Zhao, and S. Veprek Using first-principles calculations, we show that, in spite of its relatively low shear modulus, boron suboxide (B_{6} O) is superhard because of its high shear strength of ⩾38 GPa which originates from three-dimensional covalently bonded network of B12 icosahedral units connected by boron and oxy...
