different between planar vs germanene

English

Etymology

From Late Latin pl?n?rius (“relating to a plane”), derived from Latin pl?nus (“flat”, “level”), ultimately from Proto-Indo-European *pleh?- (“flat”).

Pronunciation

• (General American) IPA^(key): /?ple?n?/
• (Received Pronunciation) IPA^(key): /?ple?n?/
• Homophones: plainer, planer
• Rhymes: -e?n?(?)

Adjective

planar (comparative more planar, superlative most planar)

1. Of or pertaining to a plane.

   A planar projection of a three-dimensional object is its projection onto a plane.

2. Flat, two-dimensional.
3. (graph theory, of a graph) Able to be embedded in the plane with no edges intersecting.

   A complete graph with more than four nodes is never planar.

4. (transistor chip, semiconductor devices) Having a flat profile, not etched into a mesa.

     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.
