“…lattice parameters, strain, local chemical composition, electron potential. Nevertheless, these applications need the aid of computer programs for the simulation of HOLZ line patterns (Sung & Williams, 1991, and references therein). Software packages for the simulation of HOLZ patterns have been presented, for example, by Zuo (1992), Jouneau & Stadelmann (1998) and Vö lkl (1998).…”
