This Chip Could Change Computing Forever

I've heard, for about 20 years now, that a development just around the corner will make laptops last a week without a charge. Never happens. Color me skeptic.

10 years ago: "We gonna have graphene computers!" 10 years from now: "We gonna have graphene computers!"

When I was young...we used graphite rods encased in wood to do calculations on flat sheets of wood pulp.

Graphene is just like Nuclear fusion, always 10 years away 😅

"Imagine your phone lasting for days" Why yes, I do remember the 3310

It's intriguing how often I stumble upon a seemingly groundbreaking technology, only to discover it's been around since the mid-20th century.

Back in 2003 when I was studying Computer Science at FSU, one of the breakthroughs the university had was regarding graphene. I'm still waiting for it to materialize into ANYTHING we use daily or get a benefit out of.

Graphene breakthroughs seem to happen just often enough that makes me believe I'll never live long enough to see any graphene products.

The year is 2120... We will finally have graphene computers in 10 years!

But when will we achieve cold fusion?

Those chips will run ads faster.

I'm an ingeneer specialized in powerelectronics. We are working since around 2019 with SiC Mosfets. here are some conclusions in comparison with standard IGBT Moduls (although I obviosly can only talk about powerelectronic side, not microelectronics) - If they die (explode) they do so pretty quite, that's nice. They also don't push the silicon everywhere. I tell you, cleaning a cabinet where a IGBT did explode is annoying... - They are faster. witch IGBTs our switchingfrequency was at (depending on the output current) 2...10 kHz, with SiC we are usually at 12...20 kHz with comparable current. That reduces the losses in the chokes significantly, and reduces the noice by far. Sadly it seems, that the chokes are now at their limit. even if the output current of the Semiconductors could be increased, there are no chokes to smoothe the current out. with 25 kHz most choke technologies are also already at the optimum with copper and iron losses. - They survive overvoltages longer/easier. - they get extreamly hot, therefore the chip is a lot closer to the baseplate (wich is attached to a heat sink. sadly this increases the parasitic capasity, and because of that also EMC noise against PE. It easily interferes with other devices. An EMC Filter is mostly required. - because of the higher switching frequency parasitic problems have gone up a notch as well. For example: we build a bidirectional, galvanically isolated DC//DC converter. In the lab it worked with 30 kHz, but when we build it in a cabinet, we had to reduce the switching frequency to 17 kHz, just because the cables were a few centimeters longer, and therefore the parasitic inductance inceased. The difference is, again, the lab compared to a real application. - they are, at least for now, still very expansive All in all, it is nice, yes, but it is not the all mighty solution. All the manufacturers have already quited down significantly about innovations.

This is the same case as with batteries, every year you hear about some breakthrough tech and still your phone dies in a day with the same old lithium battery.

A little thing about graphene synthesis. There is a company out of San Diego called Grolltex which has made strides in synthesis and fabrication. Their CEO did his PhD thesis on the subject, too. The main bottleneck is not necessarily the synthesis of pristine graphene, but transferring and fabricating on different surfaces. That's what this company is trying to do. I know the sad joke about graphene being able to do anything except leave the lab, but the number of companies that are working on scaling, the number of companies working on graphene fabrication infrastructure, and also the very smart people in materials synthesis labs have put out lots of papers recently on the subject. There is one professor at Johns Hopkins who is working on graphene synthesis via CO2 splitting, which is exciting. If you're an aspiring materials scientist or chemist, this is a great field to be in right now.

Clicked the video, 40sec in: "Graphene". Rolled my eyes so hard I had to look for them on the carpet.

This isn't the first time I hear about graphene chips, but last time I checked on the subject, someone suggested a silicene alternative that - in theory - would be easier to engineer since computer chips use silicon anyway.

There's 9 Tech Readiness Levels, and a working graphene transistor is TRL 3. They still have a looooong ways to go.

Graphene based chips? This has been speculated on and teased for many, many years. I’ll believe it when I see it

Graphene is one of those technological breakthroughs that is always 10 years away. Just like Nuclear fusion. I am afraid AGI may follow the same trajectory

You mentioned the 'band gap'. Very key with this tech idea to be resolved first before it can/will be rolled out. loved the video mate.
