What will we do below 3 nm?

What will we do below 3 nm?
- zaroth 7y agoPresumably 2 nm.
- Filligree 7y agoHow many silicon atoms is that?
- bureaucrat 7y agoA silicon atom is 0.2nm.
- PixyMisa 7y agoThe funny thing is, it doesn't matter. "2nm" is just marketing; nothing about it is actually 2nm in size. But that's okay, because that was true at 7nm and 14nm and even at 28nm. So what 2nm really means is "better than 3nm".
- JohnJamesRambo 7y agoWhy do we all go along with this charade? It’s so silly and unscientific. Why can’t we just call the things correctly?
- imtringued 7y agoIt is the same reason why we use millimeters of steel as a measurement of the armor performance of tanks even though they use composites of different materials. Because it is easier to compare two numbers even if they are meaningless in reality.
- madez 7y agoIt would be better to stay quiet instead of comparing things incorrectly.
- gameswithgo 7y agothere is no correct single number to use
- dooglius 7y agoSRAM density is a pretty good single meaningful number
- sschueller 7y agoIsn't the smallest trace/spacing 2nm? Most is larger but 2nm is possible for some traces/spaces.
- imtringued 7y agoAs many as you want.
- boyadjian 7y agoNothing, we will stay at 3 nm.

- Mathnerd314 7y agoCarbon nanotubes, graphene, photonic chips, more involved silicon designs. There's no shortage of ideas, just uncertain ROIs.
- agumonkey 7y agoThe 7-5nm was said to be so much a barrier before. I'm sure this will unleash a ton of capital and brains to keep digging. ps: I heard spintronics and neutronics caught some wind on paper
- TomMarius 7y agoThere is a new exciting paper about DNA computers as well. https://www.chemistryworld.com/news/leap-forward-for-molecular-computing-as-dna-executes-six-bit-algorithms/3010270.article https://www.chemistryworld.com/news/leap-forward-for-molecul...
- agumonkey 7y agoHah, Woods of course. Two years ago a previous colleague of him hosted a talk in Paris. I got a peek of the work it was truly staggering. But the guy told me they were too instable at scale so far. Sounds like a solid hint at the future though. ps: do you work in this field ?
- TomMarius 7y agoNot at all, just an interested layperson (I'm in 'normal' IT). My partner studies evolutionary genetics (or something like that), so we talk frequently about biology. There is another DNA computing paper that was very interesting published earlier this year by another group, but I can't find it now. I think it was in Nature.
- The_rationalist 7y agoActually spintronics unlike others is ready to come to mainstream, through MRAM.
