Remarks on Prof. Michał Kokowski’s comment about the studies into the life of Prof. Jan Czochralski (in Polish) [PDF]

open access: yesStudia Historiae Scientiarum, 2016
This is a subsequent (third) part of the polemic on the facts from the life of Jan Czochralski and the difference in the presentation of these facts by amateur and professional historians.

Effect of Internal Radiation on Process Parameters in the Global Simulation of Growing Large-Size Bulk β-Ga2O3 Single Crystals with the Czochralski Method

open access: yesCrystals, 2021
As a crystal grows, the temperature distribution of the crystal and melt will change. It is necessary to study the dynamic process of single-crystal growth. Due to the relatively low crystallization rates used in the industrial Czochralski growth system,

A Coupled Approach to Compute the Dislocation Density Development during Czochralski Growth and Its Application to the Growth of High-Purity Germanium (HPGe)

open access: yesCrystals, 2023
The evolution of the dislocation density during Czochralski growth is computed by the combination of global thermal calculations and local computation of the stress and dislocation density in the crystal.

Destabilization of free convection by weak rotation [PDF]

open access: yes, 2011
This study offers an explanation of a recently observed effect of destabilization of free convective flows by weak rotation. After studying several models where flows are driven by a simultaneous action of convection and rotation, it is concluded that ...

Quasi-Transient Calculation of Czochralski Growth of Ge Crystals Using the Software Elmer

open access: yesCrystals, 2019
A numerical scheme was developed to compute the thermal and stress fields of the Czochralski process in a quasi-time dependent mode. The growth velocity was computed from the geometrical changes in melt and crystal due to pulling for every stage, for ...

From vaseline to the silicon revolution: the unusual history of the greatest Polish discovery that changed the world

open access: yesStudia Historiae Scientiarum, 2017
In August 2016 exactly one hundred years passed from the discovery of the Czochralski method of single crystal pulling, named after Jan Czochralski (1885–1953), the Polish chemist and metallurgist.
