Structure modifications in chalcopyrite semiconductors

Structure, morphology and optical properties of CuInS2 thin films prepared by modulated flux deposition

“…1. The diffraction peaks observed at 2H=27.948 and 46.908 can be generated by the (112) and the (204, 220) CuInS 2 crystallographic planes in either the sphalerite or the chalcopyrite structure [5,6]. However, the samples exhibit also a prominent series of diffraction peaks at 2H=14.408, 28.988, 44.068 and 60.108 that are generated neither by sphalerite nor chalcopyrite CuInS 2 .…”

Crystal structure re-investigation in wide band gap CIGSe compounds

“…These reflections are consistent with other possible space-groups. Among them, the space group I-42m (stannite structure type) has already been reported [17][18][19][20][21] in the CuIn-Se system (for very Cu-poor materials Cu(In,Ga) 3 Se 5 ). This structure was then used as a starting model for the studied compound.…”

Polysynthetic Twinning in RbIn3S5

“…A special property of the RbIn 3 S 5 structure is the absence of a low-indexed direction, which is exactly perpendicular to [20 % 1]. 3 Taking into account a rectangular orientation of the twin element and [20 % 1] (a=901) it is obvious that twinning by merohedry cannot be exactly fulfilled. Hence, we observed in diffraction patterns of twinned crystallites (see the enlarged sections of diffraction patterns in Fig.…”
