Ahw. Ngan et Ip. Jones, THE USE OF SUPERLATTICE REFLECTIONS FOR WEAK-BEAM MICROSCOPY, Philosophical magazine. A. Physics of condensed matter. Defects and mechanical properties, 68(3), 1993, pp. 525-535
The use of superlattice reflections from ordered compounds for weak be
am imaging is rendered difficult by the weakness of the beams and by t
he presence of nearby strong fundamental reflections. The conditions f
or successful weak beam superlattice imaging are derived and applied t
o some explicit examples.
