WebThe smaller step height of the islands can be understood if it is assumed that crystallized islands in different polymorphs co-exist on the surface. In particular, the H-phase step edges are expected to be slightly lower than the octahedral ones because the partial distortion of the latter induces a buckling of the chalcogen atoms. WebNov 1, 1998 · The curing-step, necessary for the production of SiC-fibres, leads to an introduction of nitrogen into the system. Hence, the intergranular amorphous phase will be enriched by heteroatoms (N) thus shifted the region of existence of crystallized ceramics to higher temperatures compared to pure Si–C systems, as is described by Monthioux et al..
