摘要：

The paper reports on the study of oriented carbyne layers prepared using three different techniques: (a) chemical carbonization of a poly(vinylidene fluoride) film, (b) ion sputtering of graphite, and (c) condensation of carbon vapor produced by an electrical arc. The crystalline structure of both oriented carbyne films and single crystal microinclusions were studied by electron diffraction. The electronic structure of the carbyne was studied by Auger electron spectroscopy. The one-dimensional cumulene nature of carbyne has been confirmed. On the basis of the electron diffraction data, a Patterson function was calculated. From that, a picture of the crystal potential as well as a model of the location of the atoms in the crystal unit cell have been developed. It could be shown that carbyne exhibits a layered structure.
