## Abstract This paper proposes a geometric model for crystal growth by pulling. On the basis of the model, effects of the growth processes on the evolution of crystal shape were studied. Besides some effects already adopted in practice to control the crystal diameter, our results revealed several
typically 3ยฑ5 nm in size, were used for growing the nanostructures. After the evacuation process was completed, the temperature of the system was elevated to 750 C at a rate of 20 C min ยฑ1 and the pressure was maintained at 30 kPa. Nitrogen was sent through the system at a rate of 50 mL min ยฑ1 to ac
