"The silicone carbide chips are placed inside a crucible, where they are subjected to high heat and McCarthyist accusations." Line delivered stone cold.😂
I'm watching a video about another breakthrough on a 12-year-old Core i5. If I was using 12-year-old CPU in 2004 (back from 1992) I would have been committed (and moved to a psychiatric facility asap).
If graphene can reach hundreds of GHz or even THz then it doesn't matter if power consumption goes up by 50x. The reason the transistor count is so absurdly high in today's CPUs and GPUs is because of the lack of switching speed. You roughly speaking need to increase transistor count by 70% to increase IPC (instructions per clock) by 15%. So a Pentium sized chip at 1THz would run rings around a modern core while still using significantly less power. Of cause, if the transistors can also be made as small (or thereabout) as today's leading silicon nodes, then the area of a Pentium would shrink to a pin-prick.
Keep in mind that power scales linearly with frequency. So if your transistors are twice as power efficient, you can only double your frequency, (ignoring wire resistance). If graphene transistors are faster than silicon transistors, but take more power than silicon transistors, then your chip will not necessarily run faster However, the power dissipation in the wires is the significant bottleneck on frequency, not transistor switching speed
It's simple: - the showrunner is tapped into the industry and likely an insider on a technical lead level - his primary job is doing presentations in PPT - he has multiple video projects running in paralel - so he is in the process of simultaneously making 1 history video, 1-2 technology ones and 1-2 "recent news" vids at any given time. Of course these projects vary in their state of completeness, but because of the production flow he's got something ready (or almost ready) on any given weekend. In other words: just like Perun. Aussies are like that I guess.
I did like idea of carbon nanotubes use in memory NRAM, it was announce to be in production in 2019 by Fujitsu, but never I saw it. But it have interesting mechanic how it works.
Did you just train a model of your voice to read text in your voice? It seems, there are artefacts of sound that are not normal, and it lacks excitement you would usually convey in your enunciation and intonation, and some overlapping or not well-ended word sounds, or some parts of text having high non-uniformity of speed and high monotonicity of pace.
Interesting advancement have been made towards single molecule transistor Where quantum wave effect have been used to create destructive or constructive wave, eliminating tunnelling effect
i gather graphene local interconnect would be even more important. Gate all around makes sillicon transistors far more scalable than what any current local interconnect tecnology allows, making that the bottleneck
my bullcrap meter is going off; if this was for real and not done to solicit funding, they would be deathly quiet about it. No real innovation worth its weight in gold is announced in the town square without an accompanying patent number.
There was research on the blue LED. The scientist that got to deliver it worked on past research (gladly it was published) and seemingly did not become insanely rich from that world-changing innovation. It could have been published simply because it helps humankind get one step further. Someone else will pick the work and make further progress from there (something that would not happen if they had decided to keep it a secret).
Other contrary, if you have a world shattering invention, sometimes the best thing to do is just blast it direct to the public rather than getting whacked by a megacorp when you are trying to file a patent.
@@FredericoMirandaBrandaoAlves Shuji Nakamura wasn't exactly a scientist, he was an engineer that worked for a company(Nichia) that did make $580 million from his breakthrough. After a couple lawsuits years later he did make some millions from his old company, but was mostly ate up in lawyer fees. In the lawsuits, Nakamura initially won $180 million, but Nichia appealed the case, then both parties settled for 8.1 million to Nakamura.
The more a paper gains publicity the more peer review and research it attracts, so we will see soon. P.S. you should be more skeptical of non chinese research papers, since in China they can get royally punished for publishing fabricated data... I guess one of the rare benefits of the regime. In the west (or maybe better to say outside China - looking at you LK99) you can get in legal trouble (criminal charges) only if your research led to defrauding the government.
It's the surface that is 2D. If you sandwich a ball between two planes you can have it interact like it existed in a 2D universe even tho it's 3D. This is especially true for things like electrons that really only have a radius of interaction rather than a 3D physical macro object we conventionally understand.
Could graphene act as a transistor in a next-gen chip? Scientists come to overwhelming consensus of "maybe"
Thank you, you save 15 minutes of my time lool
Graphene "maybe" can revolutionize every part of electronics.

Must be patreon
I first thought that I heard that wrong. LOL

^ This. Hasswell i7 here. 4.8 Ghz single thread. I am a man of simple needs, and I will ride this CPU out until it's death.
If it does the job... It's good
@@Im_TheSaint chances are: that i7 will outlive you.

Would be great to have all 3 of them. More transistors, less ppwer consumption and higher frequency.

You still have to cool a processor. Even if electricity is cheap, a 50x increase in heat density would be very challenging.
@@E4tHamyeah, capacitance is difficult to reduce. I'm thinking more sensitive transistors like tunnel FETs might be better.
Georgia Tech loves getting those grants. Skeptical on their stuff.
Oooooph! I've been waiting for a this research to bare fruits.
Great video as usual, keep it up.
"for fear of entering the quantum realm" That was a good line
"2D materials" sounds like some futuristic shit from a 90s scifi anime.
"Graphene can basically fo anything, except leave the lab"
Hi!!🎉 thanks for the content
Is there a big team behind the channel ? How is he throwing out high quality, long documentary at a range of more than 1 per week…

he has a backlog, that's kinda the whole thing with having the early access patreon
@@mrembeh1848 as per my intel, he is a semiconductor business analyst. I also know his identity
Asianometry is actually a wizard
Graphene for solar?
The crazy thing is that if you rotate a sheet of graphene above another at a certain angle it becomes a superconductor at room temperature
I did like idea of carbon nanotubes use in memory NRAM, it was announce to be in production in 2019 by Fujitsu, but never I saw it. But it have interesting mechanic how it works.
Oh China, this time u arent left out.

What about gold version of graphene
Remember that graohene can do anything… except leave the lab
Weird choice of color for thumbnail.
Good job, China
Be seeing you
Back in my day transistors were made of silicon and men were men :(
I'm sure you have very refined tastes in men.
Should I copyright “G-spot” semiconductor?
I hear they can be tough to find, but quite obvious once you do.

Did we ever figure out why everyone passed on black phosphorus a decade back. There was like two articles on it and it's been graphene ever since.
I have a sister named transistor (with a blister), Mister.
First to be here!
ooops i'm late this time again...
Sorry, but there are patreon responses from 2 months ago :P
Frankly I'm skeptical of Chinese scientific papers. We'll see.

@@howwitty science stopped being believable a while back. just nonsense for grant money.

Second!'

why is science so dumb?
A topological space is zero dimensional if, and only if, it has a basis consisting of sets which are both open and closed (that is, "clopen").
