Graphyne and graphdiyne nanoribbons: from their structures and properties to potential applications

Abstract

Graphyne (GY) and graphdiyne (GDY) have properties including unique sp- and sp2-hybrid carbon atomic structures, natural non-zero band gaps, and highly conjugated π electrons.

Enhanced Elastocaloric Effects in γ-Graphyne

“…32 Graphynes exhibit unique properties, including negative thermal expansion, 33 high Poisson's ratio, 33,34 negative linear compressibility, 34 and thermoelectric capabilities. 35 Computational investigations have extended to graphyne scrolls, 36 nanoribbons, 37 and nanotubes. 38 Although the acetylene chains in graphynes are substantially reactive, Solis et al 36 showed that graphynes are thermally stable structures, at least up to 1000 K.…”
