Dense, sparkling ultra-diamonds could be the next superconductors

Carbon is one of the most versatile textile in the universe , forming everything from the plumbago establish in the pencil to severely , froth diamond . But three new forms of carbon copy might make even the most breathless diamond face impossibly dull .

As you might call up from midway school science form , diamonds are the hardest minerals in the world . That ’s because the carbon atoms are set up in a uniquely tough , tightly packed crystal structure known , predictably enough , as a baseball diamond lattice . This super rigidity also mean diamond are n’t well contaminated by other substances , which gives it its clean , colorless show . Diamond ’s relatively in high spirits density means its refractive index number is also mellow , which results in its much - prized glisten and luster .

Researchers at Stony Brook University need to find out whether it was possible to make any static shape of carbon that were even denser than diamonds . They tried a bunch of different simulation at various different temperature and pressure , and ultimately they came up with three raw carbon build , or allotropes , which theoretically should be able to remain static . These have been give the downright poetic names of hP3 , tI12 and tP12 .

While none of these raw allotrope would be knockout than diamond – which think of , again for those who remember their Mohs scale , that diamonds would be able to scratch up any of these fresh forms – they ’re all between 1.1 and 3.2 % denser than diamond . That may not seem like much , but even a flimsy increase in compactness would make an appreciable difference . They ’d all have even high refractive index number , intend they would sparkle in ways even diamonds ca n’t , which would be a pretty unbelievable visual sense to see .

But this is n’t just about make business organisation for the jewellery industry . There ’s some challenging indications that these allotrope would be ideal campaigner for superconductors . Writing for New Scientist , MacGregor Campbell explain :

The simulations also propose that the three materials have band gaps – the amount of vigor needed for electron to jump from one vim level to another – that are very different to one another . One of them , tP12 , has the turgid band gap of any carbon allotrope . This unevenness may make the allotropes good candidates for superconductors – alien substances that conduct electrical energy without resistance … According to Boris Yakobson at Rice University in Houston , Texas , a large variation in dance orchestra gap implies strong interactions between electrons and packet of energy in the lattice called phonons . This in turning could conduct to the shaping of electron pairing called Cooper pairs , which are necessary for superconductivity .

It ’s all very exciting , and there ’s only one diminished problem – we do n’t in reality know how to make any of these allotrope . They should be stable forms , but just knowing that does n’t really help us make them . Vadim Brazhkin of the Institute for High Pressure Physics explicate the problem :

“ It is not clear how we can fabricate them . Using standard pristine materials , such as graphite or amorphous carbon [ an allotrope in which the mote have no crystal structure ] , we can maybe obtain a midget amount of young stuff using extreme force per unit area treatment . ”

So then , until we figure out how to make these superconducting , super - effervescent ultra - diamonds , I gauge infield are still sort of coolheaded . I hazard …
