    Default Room Temp Single Atom Transistors

    https://www.sciencedaily.com/release...0511092920.htm

    And:

    In 2012, Klimeck was part of an international team of researchers, including Purdue, the University of New South Wales, the University Melbourne, and the University of Sydney, who developed what was then considered the world’s smallest transistor using a single phosphorus atom. At that time, the single-atom transistor had to be kept in a state of extreme cold, or the equivalent of liquid nitrogen, at minus 391 degrees Fahrenheit (minus 196 degrees Celsius).

    At the time, Intel’s most advanced chip, called the Sandy Bridge, used a manufacturing process that placed 2.3 billion transistors 32 nanometers apart. The single phosphorus atom, however, was only 0.1 nanometers across.

    So....new chips, imagine how many you could fit....

    Wait until the new miniature version comes out. What will they wrap the little buggers in for shipping?
    Mr Moore (The other one) may have to codify a few changes to his law.

    Got to feel sorry for the staff members doing the stock-take.
    Entropy is not what
    it used to be.

    LOL. it's cool. Devices built with this sort of thing will make todays smartphones and tablets etc look like clunky old valve computers.

    I suspect this is more a proof of concept, rather than something usable .

    Much like quantum computing , fusion reactors , thorium reactors , flying cars
    Allways just 10 years away , for the last 50 years :-)

    You can't keep adding working transistors of any type to a finite cubic space, the limit is not whether it can be done or not by making the transistors smaller and smaller, it is the inevitable heat loss because of inefficiencies, nothing performs work without losses. The problem is that the heat from the inside has to be migrated to the outside of the block of millions/billions of transistors and connected to a suitable heatsink/s. Making things really small is a big problem because of the above and also handling during manufacture is a consideration as well.

    Small things doing lots of work ie CPU's, get really hot and the heat needs to be conducted away, the smaller it is the harder that is to do.

    No magic (zero and infinity only exist in the mind of the observer for instance) in the real Universe just rules and restrictions and they are not clearly defined in a lot of cases unfortunately.
    It's not the least charm of a theory that it is refutable. The hundred-times-refuted theory of "free will" owes its persistence to this charm alone; some one is always appearing who feels himself strong enough to refute it - Friedrich Nietzsche
