Revision as of 15:07, 7 June 2021
Compounds which
- (1) fall under the class of gemstone like compounds and
- (2) have a crystal structure similar to diamond (cubic and hexagonal)
Sometimes "diamondoid" refers to just (1). In this wiki though both will be required to be true (starting 2021-06).
Note that mixes between cubic and hexagonal are possible (along one spacial dimension) by choice of "stacking order". Mechanosynthesizing such cubic hexagonal switches in more than one dimension leads to at least controlled atomically precise line like one dimensional faults.
Contents
Example compounds
Diamond of course
- normal cubic diamond
- hexagonal diamond aka lonsdaleite.
Compounds with partial (e.g. 50%) substitution of carbon
- moissanite (this is gemstone grade transparent silicon carbide SiC)
- germanium carbide
- tin carbide – this one is not producible via thermodynamic means. Maybe it van be piezochemically mechanosynthesized.
Compounds made from other elements of the same group in the periodic table
- pure silicon
- pure germanium
- The oddball compound that is grey tin.
- ... lead rather not – it is too metallic
III-IV semiconductors
- boron nitride – Boron nitride (cubic and hexagonal) – not referring to it's graphitic polyporph
- aluminum phospide – Aluminium phosphide – this one is quite poisonous
- boron phospide Boron phosphide
- aluminum nitride – Aluminium nitride
Other
- Checkerboard pattern neo polymorphs between group IV elements and III-IV semiconductors.
