Structure, bonding, and hardness of CrB: a superhard material?
Haiyang Niu, Jiaqi Wang, Xing-Qiu Chen +5
By electron and X-ray diffraction we establish that the CrB compound discovered over 40 years ago crystallizes in the (\emph{Pnnm}) structure, in disagreement with previ…

Families of superhard crystalline carbon allotropes induced via cold-compressed graphite and nanotubes
Haiyang Niu, Xing-Qiu Chen, Shibing Wang +3
We report a general scheme to systematically construct two classes of structural families of superhard sp3 carbon allotropes of cold compressed graphite through the topological ana…
