New material could make it possible to pack more transistors on a chip. When electrons move in a phosphorus transistor, they do so only in 2D. Thus black phosphorus could help engineers surmount one of the big challenges for future electronics: designing energy-efficient transistors. “Transistors work more efficiently when they are thin, with electrons moving in only two dimensions,” says a/Prof Szkopek, “Nothing gets thinner than a single layer of atoms.”
In 2004, physicists at the University of Manchester first isolated and explored graphene and now there are other 2D materials like black phosphorus, a form of phosphorus similar to graphite and can be separated easily into single atomic layers, ie phosphorene...
