[FoxNews] Experiment with laser shows possible replacement for silicon-chips

Interesting possibilities without the need to go quantum, well something to fill the gap before we do.

Researchers at the U.S. Department of Energy's SLAC National Accelerator Laboratory reported that magnetite, a naturally magnetic mineral -- the most magnetic of all the minerals on Earth -- was found to have the fastest-possible electrical switching time. Electrical switching, or moving a “switch” from a non-conductive state to a conductive one, is the process that makes our current electrical circuits.

This is actually pretty cool. But I still don't see it as a full on replacement. I mean look at how graphene took off... jealoussmiley.gif

not to mention, that any naturally magnetic material is quite expensive...hell, I had many a science teacher that were grumbling about the cost to get some naturally magnetic material.

In a paper just published in the journal Nature Materials, researchers described their successful observation of electrical switching (that is, a forced switch from a non-conductive state to a conductive one) in magnetite, a naturally magnetic iron oxide. The ability to act as a switch that is either “on” (conducting) or “off” (non-conducting) is the basis for a transistor, which is the building block of any electronic circuit. And while magnetite itself isn’t slated to replace silicon, the work opens up the floor for other, similar materials to be studied.

Researchers showed that magnetite’s on-off electrical switch could be flipped in one-trillionth of a second—thousands of times faster than in transistors used currently. In theory, a computer made with magnetite chips instead of silicon would be that much faster than the machines we use today. But since magnetite has to be cooled to a chilly -190 °C (-310 °F) to lock its electrical charges into place, it’s not going to end up in your computer anytime soon.

But what’s cooler than the material itself is the method used to study it. Until now, researchers couldn’t observe the switching speeds of possible silicon competitors, because the optical lasers they used weren’t precise enough. Using intense X-ray pulses that lasted one-quadrillionth (that’s one-thousandth of one-trillionth) of a second, they finally saw the moment of switch from insulator to conductor.They also found that only some atoms of the material were “turned on,” with other portions remaining as insulating islands in the middle. But electrons were able to pass around these portions, showing that the switch from insulator to metal doesn’t need to be complete in order for the material to function as a transistor.

Reading comprehension, do you have it?

Holy cow, do I agree with this post. It is honestly the main reason I barely ever post nowdays, I read through the first 2 pages, and realize that only maybe 1-2 people actually read an article, the rest just read the quoted or even worse the title and than post paragraph long opinions about how it is "bad/good."

It's a shame it's become this truth be told.

This was the most exciting part for me. I just wonder what the speed comparison is between the "hybrid material" and the magnetite, and, most importantly, the "hybrid material" and current silicone technology.
