When are we getting the supposed magical meme improvements of graphene on technology?
Filters are cool and super fast transistors are great, but you would think people would have found a way to make it more accessible by now.

I remember someone posting about lightbulbs some time ago.
Nice one user. Let's keep Sup Forums as the endless pile of generals, shilling, and identity politics as it should be.

Graphmeme will never make it out of the lab.
Silicon-Germanium is the current realistic successor to Silicon, but it's expensive and not a whole lot better so it'll need to be replaced soon anyway.

Yeah, because it's up to the two of us. I'm just saying face the facts

You won't see it in enterprise products for at least 10 years. Since hp plans on implementing it you're more likely to see consumer photonic chips before graphene.

We're pretty much at a point where graphene is about to become pretty damn accessible for everyone.

And Chinks want to get on board with it too.
>The new plant will mostly produce graphene-enhanced pastes, used for coatings and as Li-Ion battery anode materials.
I sure as fuck hope this is going to end up boosting the battery tech.
Actually there's a way higher demand for high grade graphene than the current factories can produce, but things are rapidly improving.
There's a real market for it, so we can be sure to see these factories start popping up left and right pretty damn soon.
I'd say give it 5 years and there are going to be tons of places all over the world producing this stuff.
I don't think it's going to end up in CPUs though.
We're probably going to see something completely different happen with them.
Like what this guy said.
Photonic chips or something.

It'll never happen.

The problem with reading attention grabbing headlines is that they never tell the whole story. A year or so back Samsung found a way to grow graphene based crystalline transistors utilizing conventional tooling. A dozen research groups are using it one way or another in batteries, and even more are trying to use it to improve solar panel efficiency.
No one, absolutely no one, is mass producing the stuff by the ton which industry would need. No one has established safety methodology for even handling and transporting large volumes of the ram material, nor are there any clean up procedures in place if it were to be spilled. Exact same issue with carbon nanotubes, they can be incredibly dangerous if any organic tissue is exposed to them. If you breathe them in then its going to act just like asbestos spindles in your body.
Industry is about logistics and cost effectiveness. People doing neat things in a lab on a small scale to grab headlines is incredibly far removed from wide spread mass production.
SiGe is used in the insulation of source and drain wells. IBM's 7nm quad patterned process uses it as the channel.
Its not a replacement for silicon. No one is going to end up producing pure SiGe wafers as a base.

Photonic chips sounds pretty cool. What about InGaAs then?

Got any more info or reading material about this? Sounds spooky af.

What do you think the next replacement for silicon will be then? Are ICs just going to experience a hard stall once 1nm comes around?
Gabriel Cruz
It's not going to matter if we go with the light based stuff, the tech is a bit different.
They're using a different material with photonics.
Photonics use Indium phosphide (InP) instead of Indium gallium arsenide (InGaAs)
Also photonics is a field of technology that's getting a craptons of money pumped into, by investors and governments and it's making huge advances.
Not to mention they just got an actual photonic microprocessor working, just 6 months ago, pic related.

Also this is an interesting little thing.

>The cost of manufacturing a photonics chip has dropped from $230,000 to around $10,000, making the technology available for almost every startup.
Which is a pretty big thing.
I have a feeling that we're heading into this direction, rather than down the graphene road.
Parker Foster
It's hard to make things profitable and it's one of the major criteria to being available. Check out Robert Murray Smith's youtube channel.

Ok so no one told them we don't need that much yet, We need to be educating the people to use this shit first.

All kinds of info out there on it.
We are an extremely long way from that point. We'll be fabbing vertical 3nm GAAs, and likely make the leap to quantum junctions, or optoelectronic devices. When you can power a million transistors with just a couple mw for a fraction of a millisecond you no longer have to worry about self heating in stacked logic. Area scaling needn't improve forever so long as power consumption lowers, and adding more transistors becomes economical. Area scaling was just the easiest way to do that before.

>New production cells installed at the Rudolstadt test-work facility have upgraded processing ability from 10kg to 50kg slabs of graphite per cell, with a total ore feed capacity of 365kg. Talga utilizes electrochemical exfoliation to “unzip” layers of graphite at the atomic level from raw slabs of high grade Vittangi graphite, as well as a proprietary recovery and concentration process.

The link here says
>A new doctoral dissertation at Luleå University of Technology in Sweden shows that extremely small fibers such as carbon nanotubes can make their way far into the lungs, which in the worst case can present an increased risk of developing cancer.
While that is definitely a potential hazard, at worst it's the same risk as Asbestos. Potentially dangerous if handled improperly for an extended period of time but hardly "incredibly dangerous".

Bump.

I don't know shit about Graphene but it sounds like something outta Avatar lel
