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.

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 ...

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 ...
