Abstract
J. Etrillard, P. Bourges, and C.T. Lin [Phys. Rev. B 62, 150 (2000)] compared the structural description of the aperiodic structure of the so-called high-TC superconductor Bi-2212 in the incommensurate modulated structure model and in the composite model. According to neutron diffraction data, they disqualified the first one. Another calculation proves that this conclusion is not justified. The structural equivalence between both descriptions is demonstrated, using previous structural results, and using the 4D formalism for aperiodic crystals.
