Scientists from the American University of Texas at Arlington have come up with a way to electrons at room temperature to -228 degrees Celsius to cool. In the long term, this can mean that electrical devices need much less energy.
Electrons heat up due to thermal activity at room temperature. The researchers tried to take that activity to suppress without external cooling. They sent the electrons by a kwantumput. To do this, they used a chip of a structure on a nanoscale, which they successively a bronelektrode, a kwantumput, a tunnelbarrière, a so-called ‘quantum dot’, a tunnelbarrière and an electrode used.
The results of the research appeared this week in Nature Communications. The scientists claim for the first time, electrons have cooled to room temperature without external assistance. “Researchers have previously looked at, but that was only the case in which they have the complete equipment in an extremely cold bath, appropriating,” explains a professor of the university on Science Daily.
The researchers believe that when this technique is possible will ever be implemented in transistors, the power consumption of electronic devices up to ten times can be reduced in comparison with the current technology. This means that among other smartphones longer on a single charge works. In addition, say the scientists, the technology can be useful for soldiers who have smaller batteries can use, and therefore more mobile.
