This work contributes to the direct growth of bulk substrate crystals
of TSS (ternary solid solutions). A combination of our original method
s CAM-S (crystallization method providing composition autocontrol in s
itu) and COM-S (calculation method of optimal molten solution composit
ion) has been used. The crystallization process has been simultaneousl
y accelerated by low-frequency and low-energy vibrational stirring. Th
is new approach enables the growth of crystalline ingots at first with
the high constancy of the lattice parameter a, being a priori chosen
and calculated throughout the significant part of the ingot length, an
d second the experimental data have been therefore received approximat
e to 20 times faster. This approach was applied on (Ga-In)Sb TSS. The
deviation from the a constancy was less than 0.033% (0.2 pm) with a 75
mm length. Crystals possess a mosaic structure at this stage.
