| 摘要 |
The invention relates to: - a method for synthesizing carbon agglomerates containing metastable carbyne/carbynoid chains; - a method for synthesizing carbon or carbon compound allotropes from said agglomerates containing metastable carbyne/carbynoid chains; and - the uses of said methods. The method for synthesizing carbon agglomerates containing metastable carbyne/carbynoid chains includes the following steps: a) forming carbon vapor precursors, containing carbine/carbynoid chains, by decomposing a carbon gas selected from among CH4, C2H2, C2H4, gaseous toluene, and benzene in the form of vapors at a temperature T such that 1 500°C<T < 3 000°C; and b) condensing the carbon vapor precursors, obtained in Step a), on the surface of a substrate, the temperature Ts of which is less than the temperature T. The invention is particularly of use in the field of electronics. |
