Modulated Structures of Homologous Compounds InMO3(ZnO)m(M=In, Ga;m=Integer) Described by Four-Dimensional Superspace Group

Structure analysis of new homologous compounds Ga2O3(ZnO) m (m = integer) by high-resolution analytical transmission electron microscopy

“…In Fig. 2(b), based on our experience of structural studies of the compounds In 2 O 3 (ZnO) m (Li et al, 1997;Li, Bando, Nakamura, Onoda & Kimizuka, 1998) and Fe 2 O 3 (ZnO) m and the simulation results to be illustrated later, the dark dots are believed to correspond to the metalatom positions. For convenience, we refer to the dark dots located approximately in one line normal to the c o axis as one layer.…”

“…Among them, the structures of M 2 O 3 (ZnO) m (M = In, Fe) have been studied by X-ray diffraction and high-resolution transmission electron microscopy (Hiramatsu et al, 1997;Kimizuka et al, 1993;Li et al, 1997;Li, Bando, Nakamura, Onoda & Kimizuka, 1998;Nakamura et al, 1990;Ohta et al, 1996). It was reported that M 2 O 3 (ZnO) m (M = In, Fe) have an LuFeO 3 (ZnO) mtype structure consisting of MO À 2 (M±O) and MZn m O m1 (M/Zn±O) layers stacked alternately along the c axis.…”

Synthesis and Crystal Structures of InGaO3(ZnO)m (m = 2 and 3)

“…The general formula of such mixed oxides is ARO 3 (ZnO) m (m = integer; A, R = trivalent ions). Several homologous compounds of oxides of ARO 3 (MO) m (M = Mg, Mn, Fe, Co, Cu, Zn, Cd; A = Sc, Y, In, Ho, Er, Tm, Yb, Lu; R = Al, Fe, Ga) are described [9][10][11][12][13]. Aristotypes for this series of compounds are YbFe 2 O 4 (=FeYbO 3 (FeO) 1 ) [14] and In 2 ZnS 4 (=In 2 S 3 (ZnS) 1 .…”

Zigzag Inversion Domain Boundaries in Indium Zinc Oxide-Based Nanowires: Structure and Formation

“…10,11 Li et al suggested that the center of mass in the wurtzite tetrahedra gradually shifts, yielding a trigonal bipyramidal layer in the center of the slab Figure 1a. 12 Here, zigzag contrast is supposedly caused by substitution of M 3+ for Zn 2+ , which form {1212} planes that are sharply visible along the [10 1 0] zone axis. (In this work, we will use the 4 index notation of wurtzite to describe crystal directions, because these are perpendicular to the crystal planes of the same index.)…”

“…The indium layer is placed on the {10 1 1} plane, where it would be sharply visible along [1120], contrary to experimental reports. [7][8][9][10][11][12] Recent calculations using density functional theory (DFT) concluded that the model of Yan et al has a similar formation energy to that of Li et al …”
