Lj. Allen et Tw. Josefsson, CONTRAST OF HOLZ LINES IN ENERGY-FILTERED CONVERGENT-BEAM ELECTRON-DIFFRACTION PATTERNS FROM SILICON - COMMENT, Acta crystallographica. Section A, Foundations of crystallography, 52, 1996, pp. 497-498
Whilst investigating higher-order Laue-zone (HOLZ) lines in convergent
-beam electron diffraction (CBED) patterns for silicon near low-indexe
d zone axes, Lehmpfuhl, Krahl & Uchida [Acta Cryst. (1995), A51, 504-5
14] concluded that there is a strong anisotropy in the Debye-Waller fa
ctor at room temperature. It is demonstrated here that no such anisotr
opy is implied by their experimental results.
