Does your laptop sometimes get so hot that it can almost be used to fry eggs ? New technology may help cool it,and give information technology a unique twist,says Jairo Sinova,a professor.
Laptops are getting increasingly powerful,but as they get smaller they are heating up,and dealing with the excessive heat has become a headache,Sinova explains.
“The heart of the problem is the way information is processed,”Sinova notes.“Laptops and some other devices use flows of electricity to process information,and thereby also produce heat.Theoretically,excessive heat could melt the laptop,and also wastes considerable energy.”
Sinova’s research is on an alternate way to process information.“Our research looks at the spin(旋转)of electrons(电子),tiny particles that naked eyes cannot detect,”he explains.“The directions they turn can be used to record and process information.”
To process information,Sinova says,it is necessary to create information,transmit the information,and finally read it.The question is,can we change the way this is done?“The device we’ve designed arranges the electrons according to spin together with the information we want to process.We then transmit the electrons to another place in the device but with the spin still surviving,and finally are able to measure the direction of their spin through a voltage(电压)that they produce,”Sinova explains.
