The new 2D material comprises crystalline solids with one or several atom layers. Due to its naturally atomic-level thickness, the wafers possess unique physical properties and have potential applications in high-performance electronic devices. A transistor built from a single layer of a typical 2D material with a thickness of about one nanometre, outperforms the one made with the same thickness of silicon many times.
They could continue, or even go beyond, Moore’s Law, where the number of transistors in an integrated circuit doubles about every two years.
