A one-size-fits-all master equation shall pave the way towards better design of 2D material electronics. Schottky diode is composed of a metal in contact with a semiconductor. Despite its simple construction, Schottky diode is a tremendously useful component and is omnipresent in modern electronics...

UC Berkeley engineers have built a bright-light emitting device that is millimeters wide and fully transparent when turned off. The light emitting material in this device is a monolayer semiconductor, just 3 atoms thick. The device opens the door to invisible displays on walls and windows – displays that would be bright when turned on but see-through when turned off – or in futuristic applications such as light-emitting tattoos, according to the researchers...
Read MoreTransistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years’ time. Scientists have now produced nanotransistors from graphene ribbons that are only a few atoms wide. Graphene ribbons have special electrical properties that make them promising candidates for the nanoelectronics of the future: While graphene is a conductive material, it can become a semiconductor in the form of nanoribbons. This means that it has a sufficiently large energy or band gap in which no electron states can exist: it can be turned on and off – and thus may become a key component of nanotransistors.
The smallest details in the atomic structure of these graphene bands, however, have m...
