Conclusions

From the investigations carried out, therefore, we can draw the following conclusions.

An increase in the impurity (tellurium) content in the vapor phase gives rise to a decrease in the depth of the singular minimum on the (111)A face because of “contamination” of part of the kinks.

The transition to a singular maximum on (111)A at high pressures of chlorine and tellurium is due to an additional growth mechanism associated with the participation of the impurity in nucleation.

No growth-rate maximum was observed to appear on the (001) and (110) faces in the vapor phase under the same conditions.
