Lou, I've seen the same dialectic again and again between supposed silicon limits about to be reached at X.X process generation and the architectural fixes for same. But one of the main reasons silicon hasn't been replaced yet isn't technical: it's economic, And I don't mean the fact that the material is relatively cheap. The situation is analogous to other potential replacements, like electric and/or hybrid cars, or solar energy, or bioplastics and biofuels: the existing infrastructure is huge, entrenched, pervasive and profitable. Replacing it will take a lot of conscious, united effort, even if the replacing technology works just as well.
Graphene is the future. Forcing a band gap in the material was the crucial step.
However, now that it is poised to be used mainstream, how toxic is the manufacturing process of graphene? I read an article here at DN on nano-tube creation, and its bad. Graphene can't be far behind it.
Cabe, thanks for covering this news from Georgia Tech. Graphene, in various forms including CNTs, has been considered as one possible replacement for silicon for several years. This is a totally cool step forward.
The issue of shrinking transistor size and of stretchability are really two different things.
Over the last many years people have been looking for the replacement for silicon. It is interesting that this has not happened yet. Chip makers continually improve silicon manufactur and density. Other materials generally prove to be of a much lower yield or density or both. Gallium Arsenide was one of those. It could operate at higher speeds, but yield and density were poor.
The solution to reaching limits on clock speed has been architectural. Thus we have multicore machines.
It always seems to be a race between silicon getting better and something else. As you point out in the article, the first theoretical conjecture was in 1947. These things can take a long time before they go from theory to industrial use.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
