different between silicene vs germanene

English

Etymology 1

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

Noun

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.

Etymology 2

Blend of silicon +? carbene

Noun

silicene (plural silicenes)

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

English

Etymology

germanium +? -ene

Noun

germanene (uncountable)

1. (inorganic chemistry) An allotrope of germanium that has a hexagonal, planar structure analogous to graphene

     Calculating the complex dielectric function for optical interband transitions we show that the two-dimensional crystals silicene and germanene possess the same low-frequency absorbance as graphene.

     We present first-principles studies of the optical absorbance of the group IV honeycomb crystals graphene, silicene, germanene, and tinene.

     After the successful synthesis of silicene in 2012, which was followed by a surge of studies on elemental, novel two-dimensional (2D) materials beyond graphene, a daunting quest was to obtain germanene, the germanium-based analogue of graphene, already predicted to possibly exist in 2009.
