The Microscopic Diamond Anvil Cell: Stabilization of Superhard, Superconducting Carbon Allotropes at Ambient Pressure

Xiaoyu Wang, Davide M Proserpio, Corey Oses +3

A metallic covalently bonded carbon allotrope is predicted via first principles calculations. It is composed of an $s{p}^3$ carbon framework that acts as a diamond anvil cell by cons…
