Patterns resembling Kikuchi patterns have been observed with a scanning electron microscope on silicon single crystals. The contrast of lines and bands is discussed (for symmetric and asymmetric bands and for contrast inversion). The lines, circles and parabolae are explained. Across poles, lines...
The general theory of X-ray diffraction by double hexagonal close-packed crystals with stacking faults is developed. The intensity distribution in reciprocal space is derived as a function of nine parameters which represent the fault probabilities. Only reflexions with H - K 0 mod 3 are affected....
