On crystalline structure of carbyne

Dynamic Pressure Synthesis of Carbynes

“…The electron diffraction pattern (see insert in Figure 9a) from the particles showed that the d-spacings are in fairly good agreement with the reported values of the (lmodification of carbyne [23,25]. The evaluated lattice parameters were ao = 892 pm and Co =1536 pm.…”

Future Directions in Carbon Science

“…Carbynes are a condensed form of carbon featuring chain-like carbon-carbon sp 1 bonding. Carbynes have been identified in two stable phases (labeled α and β) (9,14), and both phases are hexagonal, with lattice constants: a α = 8.94Å, c α = 15.36Å; and a β = 8.24Å, c β = 7.68Å (15). Application of pressure converts the α phase into the β phase.…”

Growth and Field Electron Emission Properties of Nano-Structured White Carbon Films

“…The XRD spectrum, shown in Fig.2, exhibits the typical signature of white carbon material. The presence of the peak at 2 0 =21.68°( d=0.4107nm) in the spectrum, which corresponds to the (110) diffraction line of 0 modifications, is taken as one evidence for the existence of white carbon material [5].…”
