  2. Crystal growth - Wikipedia

    en.wikipedia.org/wiki/Crystal_growth

    Crystal growth is a major stage of a crystallization process, and consists of the addition of new atoms, ions, or polymer strings into the characteristic arrangement ...

  3. Adatom - Wikipedia

    en.wikipedia.org/wiki/Adatom

    A new type of growth, called multilayer growth, is started, instead of the layer-by-layer growth. Multilayer growth can be divided into Volmer-Weber growth and Stranski-Krastanov growth. [2] If the crystal surface contains a screw dislocation, a different type of growth, called spiral growth might take place. Around the screw dislocation, a ...

  4. Porphyroblast - Wikipedia

    en.wikipedia.org/wiki/Porphyroblast

    These microstructures are interpreted classically as having formed by shearing induced rotation of a growing garnet crystal. [1] Later research, however, led to an alternative formation model in which a porphyroblast grows over a developing microfold while maintaining a stable position in the external reference frame. [2]

    Figure 3: Ball model representation of a real (atomically rough) crystal surface with steps, kinks, adatoms, and vacancies in a closely packed crystalline material. Adsorbed molecules, substitutional and interstitial atoms are also illustrated. [3] Depending on the position of an atom on a surface, it can be referred to by one of several names.

  6. Dislocation - Wikipedia

    en.wikipedia.org/wiki/Dislocation

    Where surface relief can be resolved to the level of an atomic step, screw dislocations appear as distinctive spiral features – thus revealing an important mechanism of crystal growth: where there is a surface step, atoms can more easily add to the crystal, and the surface step associated with a screw dislocation is never destroyed no matter ...

  7. Shaping processes in crystal growth - Wikipedia

    en.wikipedia.org/wiki/Shaping_processes_in...

    Edge-defined film-fed growth or EFG was developed for sapphire growth in the late 1960s by Harold LaBelle and A. Mlavsky at Tyco Industries. [4] A shaper (also referred to as a die) having dimensions approximately equal to the crystal to be grown rests above the surface of the melt which is contained in a crucible.

  8. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    Time-lapse of growth of a citric acid crystal. The video covers an area of 2.0 by 1.5 mm and was captured over 7.2 min. The crystallization process consists of two major events, nucleation and crystal growth which are driven by thermodynamic properties as well as chemical properties.

  9. Czochralski method - Wikipedia

    en.wikipedia.org/wiki/Czochralski_method

    Silicon crystal being grown by the Czochralski method at Raytheon, 1956. The induction heating coil is visible, and the end of the crystal is just emerging from the melt. The technician is measuring the temperature with an optical pyrometer. The crystals produced by this early apparatus, used in an early Si plant, were only one inch in diameter.
