Can diamonds be annealed like silicon?
Annealing is an important step in semiconductor fabrication. The doping of silicon crystals is done by ion implantation which creates a lot of defects in the crystal lattice. Heating the crystals for ...

How many Nitrogen-Vacancies (NV) can there be in a NV-diamond?
I read on the internet that Nitrogen-Vacancies (NV) diamonds can be made as large as $\approx$ 1 gram, so I guess they can be somewhat macroscopic. But how many NV centers there can be in a diamond? ...

Why is it that other diamond lattice elements not as strong?
For example,
Germanium and Silicon with both Mohs(scratch) hardness of 6 and 7 respectively. But they also have the same tetrahedral structure.
I've seen some answers such as,
(a) The covalent bonds ...

Why can undercoordinated lattices not be described with isotropic pair potentials?
Is there a simple physical argument why lattice structures involving 3 and 4 fold coordinations as in graphite and diamond are not stable in radially symmteric pair potentials?
I read in the bond ...

Are there any materials known to be harder than diamond under high pressure as of April 2024?
This is a variation of this question where I asked if materials under high pressure can break standard pressure density records.
I am curious about materials that become superhard under very high ...

Is the difference between cubic and hexagonal diamond structure in 2 dimensions or 3 dimensions?
I was reading the book Solid State Physics by Charles Kittel. It was explained that the difference between Cubic F or FCC and the Hexagonal Closed Packed structure or the HCP was as follows -
(Please ...

What makes carbon atomic structures stand out from other elements in terms of their properties?
Since lots of materials with some remarkable properties are some form of carbon structures:
Incredible strength of graphene is often explained by it having a hexagonal atomic lattice. Hardness of a ...

Could a nuclear bomb be used as a replacement for gunpowder in a giant cannon made out of diamond?
The question is obviously outlandish, but I'm curious about the napkin-math involved in estimating this. I don't know much material science and seems like an interesting exercise.
If I could carve a ...
