Modelling of the Czochralski flow

Abstract and Applied Analysis, 1998
The Czochralski method of the industrial production of a silicon single crystal consists of pulling up the single crystal from the silicon melt. The flow of the melt during the production is called the Czochralski flow.

Melt Flow and Dopant Distribution During the Growth of Si and Ge Crystal: A Review

Chemical Engineering Transactions, 2018
Segregation occurs for most of dopants employed in crystal growth, leading to variation of dopant concentration and properties along the crystal. This article presented a review of recent research on melt flow and dopant distribution during the growth of

Obtaining and investigation of the structural features of the LiNbO3 : Zn (2,12 wt. % Zn) single crystal [PDF]

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2018
We carried out preparation of homogeneously doped charge LiNbO3:Zn ([Zn] = 2,44 wt. %) of congruent composition (ratio [Li]/[Nb]=0,96). From this charge a LiNbO3:Zn (Zn ~ 2.12 wt. %) single crystal by the Czochralski method was grown.

Preparation of large Cu3Sn single crystal by Czochralski method

Journal of the Korean Physical Society, 2022
Cu3Sn was recently predicted to host topological Dirac fermions, but related research is still in its infancy. The growth of large and high-quality Cu3Sn single crystals is, therefore, highly desired to investigate the possible topological properties. In this work, we report the single crystal growth of Cu3Sn by Czochralski (CZ) method.

Growth of piezoelectric crystals by Czochralski method [PDF]

Le Journal de Physique IV, 1994
The Czochralski method is one of the most widely used industrial technique to grow single-crystals, since it applies to a very large range of compounds, such as semiconductors, oxides, fluorides, etc... Many exhibit piezoelectric properties and some of them find applications in Surface-Acoustic-Waves or Bulk-Acoustic-Waves devices.

Hydromechanic instability of crystals growth by Czochralski method [PDF]

Вестник Чувашского государственного педагогического университета им. И.Я. Яковлева. Серия: Механика предельного состояния, 2020
Рассмотрен один из механизмов гидромеханической неустойчивости при выращивании кристаллов из расплава методом Чохральского, связанный с явлением образования «холодных термиков» в подкристальной области. С этой целью проанализированы результаты, полученные по двум математическим моделям: 1 - без и 2 - с учетом процесса кристаллизации.
