[交流] Phosphorene: the post Graphene age

Graphene, a one-atom-thick layer of carbon, has charmed materials scientists with its enticing electrical properties that allow electrons to flow freely
across its surface. But the material lacks a natural band gap — a range of energy states in which electrons cannot exist freely — that could be used to switch this flow on and off. This reduces graphene’s usefulness as a replacement for the semiconductor switches in computer circuits.
       Research groups in the United States and China reported on work towards a promising candidate that could fulfil both needs: phosphorene, an atom-thick layer of the element phosphorus that does have a natural band gap. The work is part of a trend that David Tománek, a condensed-matter theorist at Michigan State University in East Lansing, dubs the “postgraphene age” — in which researchers are exploring alternatives in the hope of overcoming
graphene’s deficiencies. The rationale is that phosphorene might be useful for making thin, flexible electronics that could be more easily cooled than silicon ones.Phosphorene: the post Graphene age
