Aiming to establish new spintronics
[Keio Spintronics Network - Nitta Laboratory , Tohoku University] School of Engineering, University:Aiming to establish new spintronics Current semiconductor technology has advanced by making things smaller. But its clear that progress in the electronics supported by smaller devices will reach a limit in the near future, in line with Moores law. At Tohoku Universitys Nitta Laboratory, researchers are working to solve this problem by focusing on electron spin. They aim to develop entirely new methods of controlling electron spin. This field of electronics using spin, called spintronics, is very topical right now. Q In our Lab, were looking for new functionalities based on electron spins, which have so far been controlled using magnetic fields. If we can control spins using electric fields, we can develop new horizons of electronics using electron spins. Thats the goal of this research. In conventional electronics, information is processed by using the on and off states of current flow as 1 and 0 in calculations. To do these calculations in spintronics, the electrons spin direction can be treated as information. So information can be processed using just the number of spins in each direction. However, controlling the direction of spin at the electron level is considered very difficult. So far, no clear method for such control has been found. Therefore, instead of controlling spin using magnetic fields, as has been done so far, the Nitta Lab is experimenting with the use of ...From:keiouniversityViews:1183 5ratingsTime:04:00More inScience Technology
