Remarkable nanowires could let computers of the future grow their own chips
If you’re worried that artificial intelligence will take over the world now that computers are powerful enough to outsmart humans at incredibly complex games, then you’re not going to like the idea that someday computers will be able to simply build their own chips without any help from humans. That’s not the case just yet, but researchers did come up with a way to grow metal wires at a molecular level.
At the same time, this is a remarkable innovation that paves the way for a future where computers are able to create high-end chip solutions just as a plant would grow leaves, rather than having humans develop computer chips using complicated nanoengineering techniques.
Researchers from IBM’s T.J. Watson Researcher Center are working to create wires that would simply assemble themselves in chips. The scientists use a flat substrate loaded with particles that encourage growth, and then add the materials they wish to grow the wire from.
Researchers used gold to drive the reaction, surrounding it with trimethylgallium and arsine gasses. The result was a gallium arsenide wire that took just a few hours to grow. The researchers also already have the ability to modify the structure to create different layers on top of each other along the length of the wire.
Using this remarkable process, researchers think they can ultimately create nanowires that have the necessary electrical properties that would allow them to form into transistors, which could be the computer chips of the future.
However, this procedure still requires human supervision for the time being, and computers can’t just upgrade themselves by building the chips they require out of thin air – at least not yet.
