HTTP:: Photons Can Manipulate Nanocrystal Magnetism
--------
Semiconductors have been the base for modern-day electronics since the first processors appeared, but, for a long time, experts have been trying to make them into structures that not only conduct electricity, but also have their own unique functions. Inspiration for this was drawn from magnets, which, for instance, perform the simple task of sticking to a refrigerator. Similarly, physicists want to be able to make semiconductors act like more than mere conveyors, they want to use them for data recording and electronic control.Up to this point, they have managed to endow the structures with such properties, but only at freezing, extremely-cold temperatures, of up to -260 degrees Celsius (-400 degrees Fahrenheit). At this point, they are learning how to use photons, the small, elementary particles that make up light, to instill these types of behaviors in semiconductors at room temperatures. Experts at the University of Washington (UW) have recently succeeded in finding a way!
to use photons successfully on semiconductor crystals, called nanocrystals or quantum dots.“This provides a completely new approach to microelectronics, if you can use spin instead of charge to process information and use photons to manipulate that process. It opens the door to materials that store in...
