In gemstone metamaterial technology covalent bonds are of most interest since they:
- are usually strongly localized (unlike metallic bonds)
- allow for passivation of surfaces making them not weld together on contact. Essential for any kind of machine with moving parts sliding over each other.
- are strong enough to not diffuse around at room temperature. (unlike metallic bonds where single atoms often like to diffusing around wildly on surfaces)
