Crystal growth involves a variety of research fields ranging from surface physics, crystallography, and material sciences to condenser mater physics. Though it has been studied extensively more than 100 years, crystal growth still plays an important role in both theoretical and experimental research fields, as well as in applications. For example, how to growth ideal high Tc superconductor crystal has become an dominant subject both for testing of superconductor theories and physical properties. Furthermore, carbon 60 and carbon nano-tubes have opened a new field to both condensed mater physics and chemistry. From the recent discoveries in high Tc superconductors and C60, which brought the Nobel prize to the pioneer researchers in this field, one can understand the importance of crystal growth today.

As the development of scientific instruments and analytical methods, such as x-rays, electron microscopy, NMR, and scanning tunneling microscopy continues, research on crystal growth an ...more

Crystal growth
From Wikipedia, the free encyclopedia

It has been suggested that this article or section be merged with Crystallization and Recrystallization (chemistry). (Discuss)

Quartz is one of the several thermodynamically stable crystalline forms of silica, SiO2
A crystal is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. Crystal growth is a major stage of a crystallization process, and consists in the addition of new atoms, ions, or polymer strings into the characteristic arrangement of a crystalline Bravais lattice. The growth typically follows an initial stage of either homogeneous or heterogeneous (surface catalyzed) nucleation, unless a "seed" crystal, purposely added to start the growth, was already present.
The action of crystal growth yields a crystalline solid whose atoms or molecules are typically close packed, with fixed positions in space relative to each other ...more

The growth of a crystal, which involves diffusion of the molecules of the crystallizing substance to the surface of the crystal, diffusion of these molecules over the crystal surface to special sites on the surface, incorporation of molecules into the surface at these sites, and diffusion of heat away from the surface.
