Electron Spins for Design of Next-Generation Information Technology

Electron Spins for Design of Next-Generation Information Technology

Scientists from Sweden’s Royal Institute of Technology and Linköping University have discovered a new concept that uses the spin property of electrons to efficiently transfer information to light at room temperature, which could pave way for future information technology. The scientist presents their concept in an article published in scientific journal called ‘Nature Communication’ on September 3, 2018.

Moreover, light and the electron charges are the main source to transfer information from one channel to other. To get information faster and in compact form with less energy intensive, the scientists across the globe are hunting for another aspects of electrons. The major problem faced by researchers is that the electrons easily lose their pins orientations when they are set at high temperature. The key benefit of the device concept the work demonstrates is that it can transfer more information at room temperature. However, scientists also noticed that at room temperature, the orientation of spin were almost randomized. As a result, the information encoded in the spin electron are too vague or may be lost to transfer in the chiral light. The researchers propose a powerful spin-light interface to overcome these constraints.

Device to pave way for New Designs of Spin-Light Interfaces

The electronics which comprises both the spins and electrons charges are specifically known as spintronics. Same as the planet Earth, an electron spins at its own axis which is either clockwise or anticlockwise and the form of rotations are referred as spin-up and spin-down position. The device researchers have developed helps in carrying information contained in electron spins to light, which can then be carried further using fiber optics over long distance.

Scientists demonstrated that the device can improve the signals transmitted by electron spin by removing the defects. Moreover, less than one out of overall million gallium atoms are moved from the chosen lattice sites in the device. They believe that the device will be used to enhance new designs for spin-light interfaces, which will pave way for promising opto-spintronics applications.
