| The crystal growth of Zo is made easy by the fact that zo has a congruent melting point. The molten zone was very stable for the entire duration of the growth procedure. The power needed to melt the rods was about 55％ of the total output power of the lamps. However, there is a serious problem that many bubble inclusions observed in a crystal grown at 10 mm/h with the rotation rate of 30 rpm as shown in Fig. 2(a). S.M. Koohpayeh et al.[20] reported that bubble-free rutile single crystals were grown with a 0 rpm rotation rate. In spirit of that, lower rotation rates of 10 (sample 1)and 5 (sample 2)were applied in the later work. The crystal wafers cut perpendicular to the growth direction were observed with polarizing microscope. There were few bubble inclusions in the sample 1. Sample 2 is free of bubble inclusion. In conclusion, a lower rotation rate is effective to suppress the formation of bubble inclusion in growth of zo crystal. |
