Diamond press creates crystalline hydrogen. Does this mean a replacement for silicon?

In the tests the scientists were able to produce pressures around 3.5 million atmospheres. This compressed the hydrogen so much that it began to reach the stage that it acts like a metal. This has been hypothesised since the 1930s and is believed to be able to dramatically improve the performance of computers as it will replace ageing silicon technology. It may also provide new ways of storing fuel for hydrogen cars and may also be used as a rocket fuel.

 

"We think we've reached a state of the material that is probably the precursor to metallic hydrogen," explained Ross Howie

3.5 million atmospheres? Pressure's on.

 

Bad joke, sorry.

Cool, but good luck packaging 3.5M atmospheres in something that could be useful in the consumer market, not to mention the material itself needs to have chips printed on it and it can't do so if as soon as you remove the pressure it vaporizes (or just blows up as hydrogen likes to do).

Don't ask to ask, just ask... please 🤨

I like that they're excited about possibly having a room temperature superconductor... at 3.5 million atmospheres. The reason room temperature superconductors would be great is that cooling superconductors cryogenically is impractical and expensive. You know what else is impractical and expensive? Yeah, creating pressures of 3.5 million atmospheres.

Well metal is itself crystalline, so metallic hydrogen is the next logical step.

Yeah, hardly anytime soon we'll see silicon replacement on consumer side. Can't even get new type of batteries that can last significantly longer...

Metallic Hydrogen has been touted as the "holy grail of high pressure physics" for a while. This is the same type of hydrogen phase that has long been predicted to reside near the cores of gas giants.

 

This isn't something that can really be used for electronics. Electrics on the otherhand? Maybe. But at the atmospheres needed, even with theoretical lithium doping, it's not likely to be what makes the world-saving superconductor we're all looking for. But it's still good news.

to replace silicon wont they need a semiconductor not a superconductor?

Yes, but they mention both as possibilities, as well as other stuff like better rocket fuel.

I am probably misunderstanding the physics behind it, but given my limited knowledge, can I expect someone's computer (should it overhead enough) to literally explode, like with gaseous hydrogen?

Whoever would think this is a bad joke? I laughed out loud.

I am not a scientist but I think that once it's in a solid form the element becomes stable. Just like wood.

I know that the focus of this is to make H(s) but the diamond bit reminds me of the ship armor codex entry in Mass Effect where diamonds (with some other stuff) are crushed with mass effect fields to produce a stronger and more durable material. Really awesome that we have the tech to compress H2(g) into H(s). Curious as to how the H is structured when it's solid... a diagram would be nice.

Possible laser applications? Refractive index unknown but sounds like it'll be lower than anything else.

In case the moderators do not ban me as requested, this is a notice that I have left and am not coming back.
