Invented the light switch on the basis of one molecule


Invented the light switch on the basis of one molecule  The it industry is constantly reduce in size components and devices with the goal of better adaptive work. The radical field of molecular electronics is developing this process to the limiting values: a creation of electronic networks and devices from a single molecule. Researchers from the University of Beijing has created a switch that can move from one stable position to another after irradiation with just one photon, which opens the way for technologies that can be used in photonic computers that use light instead of electricity.
Scientists are developing the area light-electronics for several reasons light travels faster than electricity, and require less energy. Previous attempts to create a component from a single molecule were unsuccessful, the switches are blocked in any one position, or not included different type of light. Researchers from Beijing used a variety of materials that helped to stabilize the light switch in one of two binary positions.
In addition, unlike most components of the same size, this switch can withstand up to one year of active work.
"In most cases the molecular components have a shelf life of minutes, hours and in very rare exceptions days," says John, Baldea from the University of Heidelberg, Germany.
Of course, we are still far from the introduction of such components in mass products, but it was a start, and everything is a matter of time.

All about that there is best in the world of the electronics!
