Graphene gets competition as a semiconductor: Black arsenic-phosphorus

9 julio 2015

Graphene, the only one atom thick carbon network, achieved overnight fame with the 2010 Nobel Prize. But now comes competition: such layers can also be formed by black phosphorus. Chemists have now developed a semiconducting material in which individual phosphorus atoms are replaced by arsenic. In a collaborative international effort, American colleagues have built the first field-effect transistors from the new material.
