because while diamond forms with a tetrahedral arrangement in its carbon lattice (known as diamond cubic), lonsdaleite forms a hexagonal one that increases thermal stability and hardness.

For instance, carbon-derived materials like graphene are ... where atoms are arranged in an ordered (crystalline) hexagonal ...

The transition that determines the micro-structure of the alloy is a solid-state process: Austenite <-> Ferrite + Cementite Austenite is stable above 727 C and is an interstitial solid solution of ...

Given the high quality of the carbon lattice, electrons move ballistically, that is, without scattering, for several hundreds of nanometres even at room temperature. This feature makes graphene a ...

Graphene is a revolutionary material composed of a single layer of carbon atoms arranged in a hexagonal lattice ...

SiV centers consist of a silicon atom positioned between two vacant carbon lattice sites in diamond. The silicon atom is located at the center of a split-vacancy configuration, with the two missing ...

displaying a network of irregularly arranged carbon atoms (shown by the red lattice lines) with varying bond lengths (indicated by numerical values) and bond angles (shown in degrees). The colored ...
