1. ECCI principles and issues

The technique of Electron Channelling Contrast Imaging (ECCI) was developed in 1967, following Coates' chance observation of an unexpected back-scattered electron (BSE) contrast produced by a thick, single-crystal sample of gallium arsenide GaAs analyzed in a scanning electron microscope (SEM). . The BSE micrograph shown in figure 1 was produced at very low magnification.
