silicene

Blend of silicon +‎ graphene, due to the similarity of the silicon layer to carbon in graphene.

silicene (countable and uncountable, plural silicenes)

1. (inorganic chemistry) A 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.

     The electronic properties of silicene nano-ribbons and silicene sheets were found to resemble those of graphene.

Blend of silicon +‎ carbene

silicene (plural silicenes)

1. (organic chemistry) Any short-lived, reactive species R₂Si: analogous to carbenes.
