Objective
The fundamental problem of interplay between bonding nature of carbon phases and their physical properties is proposed to study using several novel forms of metastable solid carbon. These forms can be prepared by high pressure - high temperature treatment of recently discovered modifications of carbon, fullerites and carbynes. Unlike well-known crystalline carbon modifications with sp, sp2, or sp3 hybridisation of atoms these pressure-synthesized novel phases constitute a new class of carbon materials, crystalline and amorphous phases with the intermediate average coordination number and average valence. Appropriate choice of starting material and variation of pressure-temperature conditions allows to vary continuously in a controlled manner the average coordination number and average valency of carbon atoms from 2 to 4, to change the topology of prepared structures, and to control the morphology of heterogenous carbon phases. In order to understand the relation between their valence state and properties, it is necessary to study structural characteristics, thermodynamic and mechanical properties, electronic transport, optic properties and chemical stability, depending on the fractions of two-, three-, and four-fold coordinated carbon atoms for new carbon phases.
High pressure synthesis is a powerful tool to prepare new metastable carbon phases. C13 NMR, XANES, EXAFS, and Raman spectroscopy investigations are expected to give a deep insight into bonding nature of the new carbon modifications. Detailed study of optical properties, stability, thermodynamic, electrotransport and mechanical characteristics will allow to establish the correlation between the average valency, topological structure and physical properties, and to find out possible technological prospects of the new materials.
The valence states of carbon atoms and structure of new carbon phases will be investigated providing detailed information on nearest-neighbour coordination and carbon network topology. The interplay between bonding nature of new carbon phases and their properties will be clarified on the basis of detailed picture of the characteristics investigated. Critical values for the average carbon valency corresponding to drastic changes of electrotransport and mechanical properties are suggested to be established. All results of the Project will be published in international and Russian journals in order to reach national and international auditorium.
