“…Hence, it is lacking a strong crystal chemical differentiation of both elements in contrast to the crystal structures of InPd 2 and In 3 Pd 5 , making it more prone to a possible occupational In/Pd disorder and compositional variation. The latter can be confirmed from phase diagrams exhibiting a homogeneity range in In 1+x Pd 3−x from 24.8 to 26, and at temperatures above 1340 K even up to 27 atomic percent indium [41]. In accor- Unfortunately, indium and palladium are difficult to distinguish by X-rays (49 vs. 46 electrons).…”

“…In view of this new structural model, the question arises, whether the X-ray diffraction data in the older literature [41] were mistakenly assigned to the TiAl 3 -type, because the disorder was hidden by the almost equal scattering factors of indium and palladium for X-rays. Another possibility, however, is that synthesis conditions such as temperature or the presence of mineralizing agents, as, e. g., iodine as applied in this work, do influence the order in InPd 3 , and the structure described here therefore represents a new modification of InPd 3 .…”

The ternary indium palladium intermetallics In 3 Pd 5 , InPd 2 , and InPd 3 have been synthesized by iodine-catalyzed reactions from the elements. Rietveld refinements on X-ray powder diffraction patterns provide the first accurate crystal structure data for (8) pm, Co 2 Si-type). X-Ray powder diffraction apparently confirms the TiAl 3 structure type proposed in the literature for InPd 3 . However, Rietveld refinement on neutron powder diffraction data reveals an In/Pd distributional disorder. Therefore, we describe the crystal structure of InPd 3 in a AuCu-type model instead (P4/mmm, No. 123, a = 287.224(4), c = 380.079(7) pm), with mixed occupancy of one crystallographic site by 50 % In and 50 % Pd. In contrast to In 3 Pd 5 and InPd 2 , which can be considered to be line compounds, InPd 3 shows a non-negligible homogeneity range with unit cell volumes ranging from 0.126132 (5)

“…Furthermore, we note that the In concentration in the InPd phase is very stable throughout its entire compositional range due to its low chemical potential. 35 The fact that the chemical compositions of post-growth catalysts of both nanowires and nanorods are identical suggests that In might be expelled from the smaller catalysts to reach the stable BCC In-Pd phase when the nanowire growth was terminated. Evidently, a "necking" phenomenon is observed in all nanowires [refer to Fig.…”

In this study, Pd was used as catalyst to grow one-dimensional InAs nanostructures on GaAs (111)B substrates in order to explore the growth mechanism and the effect of non-gold catalysts in growing epitaxial III-V nanostructures. With detailed morphological, structural, and chemical characterizations using electron microscopy, coupled with analysis of the Pd-In binary phase diagram, it was found that size of Pd nanoparticles plays a key role in determining the growth mechanism of one-dimensional InAs nanostructures.

The binary Pd‐Zn system was assessed in the scope of this paper. The experimental data from the literature were used for the assessment, together with our own data obtained by SEM‐EDS analysis and by the DTA. The paper is focused particularly on the Pd‐Zn system, but the Pd‐Sn and Sn‐Zn systems are also analysed in this paper. Finally, first prediction of the isothermal sections of the ternary Pd‐Sn‐Zn system was made.
