Figure 4From: Homogeneous crystalline FeSi2 films of c (4 × 8) phase grown on Si (111) by reactive deposition epitaxyTop views of the structure models for iron silicides. (a) The 2 × 2 structure model. (b) The c (4 × 8) structure model proposed by Krause et al. [2, 12]. A rhombic unit cell and a parallelogram unit cell are outlined in (a) and (b), respectively.Back to article page
