モルフォロジーに及ぼす回転双晶の影響

抄録

Some of the crystals, such as CdTe, GaP and ZnSe crystals with zincblende structure, contain rotation twins. They are classified into two types: one is rotated around the <111> growth direction and the other around one of the <111> directions other than growth direction. The existence of the rotation twins around the growth axis can be identified by the orientation of isosceles triangular etch pits developed either on the {011} cleavage plane or on the growth habit plane. The existence of the other twins was recognized by the etching behavior on {511} and {111} planes of the CdTe crystal and measurement of the angle between the two element whiskers of GaP.
