This review provides a discussion of the current state of research on linear carbon structures
and related materials based on sp-hybridization of carbon atoms (polyynes and cumulenes) …

Linear, sp-hybridised, 1-dimensional (1D) all-carbon wires are conceptually the simplest π-
conjugated organic molecules. Their fundamental experimental and theoretical properties …

Strong chemical activity and extreme instability in ambient conditions characterize carbyne,
an infinite sp 1 hybridized carbon chain. As a result, much less has been explored about …

We report an extensive study of the properties of carbyne using first-principles calculations.
We investigate carbyne's mechanical response to tension, bending, and torsion …

Besides graphite and diamond, the solid allotropes of carbon in sp2 and sp3 hybridization,
the possible existence of a third allotrope based on the sp-carbon linear chain, the carbyne …

The first electrical-transport measurements of monatomic carbon chains are reported in this
study. The chains were obtained by unraveling carbon atoms from graphene ribbons while …

First-principles calculations for carbyne under strain predict that the Peierls transition from
symmetric cumulene to broken-symmetry polyyne structure is enhanced as the material is …

Linear carbon chains (LCCs) are a one-dimensional sp 1-hybridized allotrope of carbon.
LCCs are extremely unstable: The longer the LCCs, the less stable the materials. Thus, it is …

Ultralong linear carbon chains of more than 6000 carbon atoms have recently been
synthesized within double-walled carbon nanotubes (DWCNTs), and they show a promising …

The electronic structure of graphene antidot lattices (GALs) with zigzag hole edges was
studied with first-principles calculations. It was revealed that half of the possible GAL …
