Researchers developed world's smallest diode

                Researchers from the University of Georgia and Ben-Gurion University of the Negev (BGU) developed the world’s smallest diode, the size of a single molecule. The breakthrough could impact the development of molecular electronic devices. Their study was published in journal Nature  Chemistry on 4 April 2016. The nanoscale diode or molecular rectifier operates like a valve to facilitate electronic current flow in one direction. A collection of these nanoscale diode, or molecules, contains properties that resemble traditional electronic components, such as a wire, transistor or rectifier.
