Title: Method of controlling dislocation
Inventor: ONO HARUHIKO
IPC: C30B33/00
Filed: 1987-08-07
Abstract: PURPOSE:To control the kinds of dislocations and introduce dislocations into a binary compound crystal having zinc blende type crystal structure by using twins in which two crystals having orientation relationship, in which the orientations of main slip planes are symmetrized mutually to an axis vertical in the direction of stress, are coupled on a specific crystal grain boundary. CONSTITUTION:The crystal orientations of the upper section 1a and lower section lb of a sample 1 are made to differ, holding a crystal grain boundary 2. A crystal in the upper section 1a and a crystal in the lower section 1b have orientation relationship in which the orientations of main slip planes (1-11) are symmetrized mutually to an axis vertical to the direction of stress. When tensile or compressive uniaxial stress P is applied in the direction parallel with the grain boundary 2 to the sample 1, the signs of the main slip planes are exactly reversed in the upper and lower sections of the sample 1, holding the grain boundary 2. Consequently, a beta dislocation is introduced to the upper section 1a from an upper surface and the beta dislocation to the lower section 1b from a lower surface. Accordingly, the kinds of dislocations are controlled and dislocations are induced.
