The thickness of the QLLs is different on different faces, and becomes thinner as the temperature is decreased. Thus, the temperature at which a QLL disappears depends on the face. When the surface is covered by Q.LLs, crystal growth is regarded as a solution or melt phase growth, whereas on a naked surface it is due to vapor growth. Thus, the repeated Habitus change may be explained. The presence of QLLs was confirmed by ellipsometry.

Based on these analyses on the SiC coating, the growth mechanism of the SiC layer on diamond is considered as follows. In the early stage of the SiC formation on diamond, a very thin SiC layer is formed on the diamond surface according to reaction (10.2) between diamond and SiO(g). Once the SiC layer is formed, this reaction does not proceed due to the protective layer of SiC. The carbon sheet and felt in an alumina crucible act as the carbon source. The reaction of C02(g) with these carbon sources will produce further CO(g) and deposit SiC(s) by reaction (10.7). Thin j3-SiC whiskers are observed on the surface of the SiC-coated diamond, suggesting the vapor growth of SiC.

A CdTe layer 12 is formed over the structure by the use of a vapor growth method. Thereafter, an HgCdTe layer 14 is formed over the CdTe layer.

This field of research on the vapor-growth of ZnO has been reactivated from 1998 by the need of ZnO substrates for growing epitaxial structures in view of photonic applications. 

From this variation of the growth rate with time and from the small A// value, compared to the ZnSe one, we suggested that the vapor growth of ZnO with hydrogen occurred according to a complex chemically assisted sublimation mechanism involving a competition between two different mechanisms, one associated with ZnO, the other with Zn.
