Abstract
The principle of dark field imaging is comprehensively discussed using real images of dislocations, stacking faults and gettering phenomena due to defects obtained by Cz Si wafers and LEC semi-insulating GaAs crystals. Resulution of dark field imaging is improved by Fourier transformation of Fraunhofer diffraction pattern obtained at an out-of focusing position of an objective lens.
