Three types of dislocations are identified and their Burgers vectors are determined from a number of topographs having different diffraction vectors and recorded on the same film at a time. Straight dislocations are found to be edge dislocations and their Burgers vector is h1 1 0i. Also mixed dislocations are found. The overall dislocation density is about 2000 cm À2. Large stacking faults are limited by long straight dislocations, the Burgers vector of which is h1 1 0i. Only a few threading dislocations are observed in the epitaxial layer grown by vapourphase epitaxy. Their density is about 500 cm À2. Small circular dots found are interpreted as indium-rich inclusions.

Jadi, tujuan pendidikan bukan memintarkan tetapi membuat orang terbuka dengan berbagai gagasan.
