Witryna4.2.1 Czochralski method. The Czochralski (CZ) method is a crystal growth technology that starts with insertion of a small seed crystal into a melt in a crucible, pulling the seed upwards to obtain a single crystal. The method is named after the Polish scientist Jan Czochralski, who developed it in 1916. Witrynaconcentration of the impurity in the solid to that in the liquid at the interface, i.e. k o = C s /C l. Table 2.2 lists the equilibrium segregation coefficients for some common impurities and dopants. Note that all are below unity, implying that the impurities preferentially segregate to the melt and the melt becomes
