Growth form determinate

Tracht change differs from change in Habitus in that it describes a change in the form of a crystal grown in an isotropic environmental phase through the combination of different faces and the relative sizes of respective faces. Therefore, Trachts are forms determined by the relative ratio of the normal growth rate R of the different crystal faces present on the surface of a growing crystal. The... 

Growth forms are the forms of a crystal determined by the structural characteristics and the effects due to environmental conditions. Assuming that a growing crystal is bounded by two F faces only, the Tracht of the crystal is determined by the... 

The dependence of growth forms on overpotentials originates from the potential dependence of nucleation and growth processes. Competition between nucleation and growth processes is strongly influenced by the potential of the cathode. Thus, major factors determining growth forms are as follows ... 

The SiHj radical physisorbs on the a-Si H surface and recombines there with another SiH radical to form disilane Si2 Hg, or abstracts H from the surface to form a dangling bond and SiH. The film growth is determined by the chemisorption of the SiH radical on a free dangling bond site by formation of a Si-Si bond. The cross-linking of...
