Secondary Phase CeO₂ Precipitates in Ce,Er-Doped Na_0.5La_0.5MoO₄ Single Crystals Grown by Czochralski Method

Crystals, 2023
Analytical scanning and transmission electron microscopy were used to study the microstructure of Ce,Er-doped Na0.5La0.5MoO4 laser crystals. Crystals were grown by the Czochralski method from the melts with a nominal composition of Na0.5La0.5−xCexEr0 ...

Electromigration process for the purification of molten silicon during crystal growth [PDF]

, 1982
A process for the purification of molten materials during crystal growth by electromigration of impurities to localized dirty zones. In the Czochralski crystal growing process, the impurities are electromigrated away from the crystallization interface by

Investigating the Structural Factors Influencing the Magnetic Interaction between Individual Copper Spins in the CuCu4 Metallacrown Complex, from Its Bulk Form to Its Adsorption on Au(111)

Advanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.
The Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) is studied to examine how geometric transformations affect magnetic coupling between copper spins by using ultraviolet photoemission spectroscopy and DFT calculations for the bulk phase and CuCu4 adsorbed on Au(111). While adsorption minimally affects tDOS, exchange coupling constants between

Growth of Oxide Laser Crystals by Czochralski Method

Acta Physica Polonica A, 2013
The growth of series of actual laser crystals belonging to di erent structural types by the Czochralski method is presented. The primary attention is given to single crystalline compounds and their solid solutions with garnet structure (scandium-containing rare-earth garnets with general formula {LnSc}3[ScMe]2Me3O12, Me = Al, Ga) as well as with ...

Controlled growth of single-crystalline metal nanowires via thermomigration across a nanoscale junction

Nature Communications, 2019
Inspired by the traditional Czochralski method of growing single crystal from liquid, the authors demonstrated that at nanoscale, metallic nanowires including Al, Ag, Cu and Sn can be controllably grown from the surface of a hot solid, by simply drawing ...

Numerical Analysis of Difficulties of Growing Large-Size Bulk β-Ga₂O₃ Single Crystals with the Czochralski Method

Crystals, 2020
The difficulties in growing large-size bulk β-Ga2O3 single crystals with the Czochralski method were numerically analyzed. The flow and temperature fields for crystals that were four and six inches in diameter were studied.
