Reverse Hall-Petch effect in ultra nanocrystalline diamond
Ioannis N. Remediakis, Georgios Kopidakis, Pantelis C. Kelires
We present atomistic simulations for the mechanical response of ultra nanocrystalline diamond, a polycrystalline form of diamond with grain diameters of the order of a few nm. We c…
Softening of ultra-nanocrystalline diamond at low grain sizes
Ioannis N. Remediakis, Georgios Kopidakis, Pantelis C. Kelires
Ultra-nanocrystalline diamond is a polycrystalline material, having crystalline diamond grains of sizes in the nanometer regime. We study the structure and mechanical properties of…
Structure, elastic properties and strength of amorphous and nanocomposite carbon
Ioannis N. Remediakis, Maria G. Fyta, Christos Mathioudakis +2
We study theoretically the equilibrium structure, as well as the response under external load, of characteristic carbon-based materials. The materials considered include diamond, a…
