Characterization of the deposited thin films: (a) The Raman spectrum. (b) The schematics of the structure of a single carbyne wire. The kinks (step-like defects of the linear chain) are formed by two carbon atoms connected by a single C–C bond. The the lattice constant c is 2.57 Å for a polyyne chain. (c) The electron diffraction pattern of a thin deposited layer. The reflexes are labeled with the corresponding Miller indices. The insert shows the corresponding real-space structure of a carbyne crystal in the direction perpendicular to the chains. The parallel chains are hold together by the van der Waals interaction.
