Tricarbon: two novel ultra-hard metallic carbon allotropes from first-principle calculations

Samir F. Matar, Jean Etourneau, Vladimir L. Solozhenko

Based on crystal chemistry considerations and quantum density functional theory ground state calculations, rhombohedral rh-C3 and hexagonal h-C6 carbon allotropes are proposed and…

Crystal chemistry and ab initio investigations of ultra-hard dense rhombohedral carbon and boron nitride

Samir F. Matar, Vladimir L. Solozhenko

Rhombohedral dense forms of carbon, rh-C2 (or hexagonal h-C6), and boron nitride, rh-BN (or hexagonal h-B3N3), are derived from rhombohedral 3R graphite based on original crystal c…

B12C2N Interstitial Boron subcarbonitride with peculiar magnetic properties: First principles investigations

Samir F. Matar

The subcarbides B12C3 and B13C2 known for their abrasive properties, can be structurally considered as carbon inserted rhombohedral alpha-B12 and expressed as B12{C-C-C} and B12(C-…
