silicene

plural silicenes

1. countableuncountablechemistryA monolayer of silicon atoms packed together to resemble graphene.

   Thus, silicene has the same structure as a graphene sheet but it is composed of Si atoms instead of C atoms.

   However, silicene, the counterpart of graphene for silicon has not been found until now, although it has attracted strong theoretical attention since several years.
