    Two indium-induced Si(111) reconstructed surfaces, the (√3×√×)R30° and the (4×1) structures, were examined by dynamical low-energy electron diffraction I-V analysis. As suggested in former studies, the T4 model of the (√3×√3)R30° structure showed the best agreement with the experiments. For the (4×1) structure, we examined 45 models and selected the model proposed by a surface x-ray diffraction study as the most appropriate structure. The low-temperature phase, whose diffraction pattern is (8×1)-p1g1 with half-order streaks, has I-V curves almost identical to those of the (4×1) phase. Therefore, the structural changes accompanying a phase transition between the (4×1) and (8×1)-p1g1 structures should be very small.
