This conceptual illustration of a computer based on 2D molecules displays an actual scanning electron microscope image of the computer fabricated by a team by researchers at Penn State. The keyboard features highlighted keys labeled with the abbreviations for molybdenum disulfide and tungsten diselenide, representing the two 2D materials used to develop the transistors in the computer.

Silicon is king in the semiconductor technology that underpins smartphones, computers, electric vehicles and more, but its crown may be slipping, according to a team led by researchers at Penn State.
In a world first, they used two-dimensional (2D) materials, which are only an atom thick and retain their properties at that scale, unlike silicon, to develop a ...
