Aix-Marseille University researchers have created a two dimensional material germanene using gold substrate. Germanene is formed from single layer of germanium atoms, much like graphene, which is formed from single layer of carbon atoms.
Graphene has excellent conductivity and strength. Germanene was first introduced in 2009 and was suggested as a game changer in the electronics industry. However, during the past five years, research teams could not advance much in mass production or use of germanene.
