Abstract: | The problem of growth dynamics for crystals of binary solid solutions, obtained by the constitutional supercooling of the
melt with a silicon feeding rod, has been solved within the Pfann approximation. The dependences of the change in the axial
growth rate of Ge1−x
Si
x
crystals (0 ≤ x ≤ 0.3) are calculated. It is shown that the Ge1−x
Si
x
crystallization rate significantly changes during growth. The results make it possible to determine the optimal conditions
and technological parameters for growing Ge1−x
Si
x
single crystals (0 ≤ x ≤ 0.3) with a specified concentration gradient along the crystallization axis. |
