Twin Defects in Ce:YAP Crystal

Li Hong

Abstract

The twin defects in Ce:YAP were investigated by using synchrotron radiation topography and etch figures.The results show that the twins are {101} and {121} types,and the exchange of neighboring lattice parameters is considered to be the intrinsic factor for twining.Based on such analysis,the twin structure model was established.Otherwise,the growth experiment results show that the abrupt change of growth rate during shoulder formation tends to cause twining.
