Ba5Ti12Sb19+x, a polar intermetallic compound with a stuffed γ-brass structure
Journal of Solid State Chemistry, 2009Abstract The polar intermetallic compound Ba5Ti12Sb19+x (x⩽0.2) has been synthesized by reaction of the elements. Single-crystal X-ray diffraction analysis revealed that it adopts a new structure type (Ba5Ti12Sb19.102(6), space group P 4 3 ¯ m , Z=2, a=12.4223(11) A, V=1916.9(3) A3).

Polarity effect of electromigration on intermetallic compound formation in SnPb solder joints
Acta Materialia, 2009Abstract The polarity effect of electromigration on the interfacial reactions of micro ball grid array (μBGA) solder joints was studied in terms of microstructural evolution. A dummy μBGA package with the same pair of solder joints was used to obtain reproducible results for a practical application.

Electronic and optical properties of polar intermetallic compound BaSn3: First principles study
Optik, 2020Abstract The electronic and optical properties of intermetallic compound BaSn3 are investigated at high pressure from the first principles density functional theory calculations using the plane-wave pseudo-potential method within generalized gradient approximations in the forms of PBEsol (PBEsol-GGA).

Probing magnetism of alloys and intermetallic compounds by spin polarized photoemission (invited)
Journal of Applied Physics, 1982The potential of spin polarized photoemission for studies of alloys and intermetallic compounds is described, specifically with respect to its surface sensitivity. We present studies on well defined Ni1−xFex (100) surfaces for x = 0.2 and 0.6. We find that the majority spin band in the bulk is not full for x = 0.6.

Abstract From a detailed analysis of the self-polarization field obtained from NMR experiments on several rare-earth nuclei in the RAl2 series, we obtain reasonable estimations of the local orbital, spin and quadrupolar polarization of 5d conduction electrons: 〈lz〉d⩽0.06, 〈sz〉d⩽0.09, 〈lz2-2〉d⩽0.05.

AbstractIt is demonstrated that the hexagonal title phase exhibits a rich interstitial chemistry in which at least 18 different elements Z (C, O, Al, Si, P, S, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Ru, Ag, Sb) with a wide variety of normal valence requirements can be bonded in the center of octahedral Zr6Sb6 units.

In situ observation of electromigration (EM) has been carried out on cross-sectioned copper/tin–copper/copper (Cu/Sn0.7Cu/Cu) line-type interconnects. The surface vertical variation after EM is measured by step profiler, which indicates serious mass migration during EM. The EM rate is calculated using two distinct methods, in situ mark movement and the

AbstractA deep cathodic polarization has been applied to a Platinum/Polycrystalline Yttria Stabilized Zirconia interface under low oxygen pressure. In the temperature range 973–1273 K the Electromotive Force recorded after the current cut off did not show any rest potential at a level corresponding to nucleation of a zirconium metal phase, likely ...
