TL;DR: Scandium dysprosium antimonide ScDySb was synthesized from scandium metal and DySb in an all-solid state reaction at 1770 K as mentioned in this paper.
Abstract: Scandium dysprosium antimonide ScDySb was synthesized from scandium metal and DySb in an all-solid state reaction at 1770 K. According to X-ray analysis of the crystal structure [P4/nmm, Z = 4, a = 430.78(1) pm, c = 816.43(4) pm, R1 = 0.0238, wR(all) = 0.0688, 268 independent reflections], ScDySb adopts the anti-PbFCl type of structure, but with pronounced deviations in structural details, which are related to specific bonding interactions between the atoms involved. ScDySb shows antiferromagnetic ordering below 35.4 K, which was verified by susceptibility, heat capacity, and resistivity measurements. X-ray structure determination, performed at 30 K, showed no significant structural changes to occur during the magnetic phase transition. The band structure was calculated in the framework of Density Functional Theory. The bonding properties are comparable to those of Sc2Sb. Pronounced basins of the Electron Localization Function (ELF) appear in the tetragonal pyramidal Sc4Dy voids.

TL;DR: In this article, the effect of Sb on the effective interband transition (IBT) was investigated in InGaAs/AlAs lattice matched to InP and showed that Sb would act as a band modulator from type-II to type-I.
Abstract: InGaAs/AlAsSb systems lattice matched to InP have two distinguishable features: a high conduction band offset and type-II band configuration. Although, the former results in a large intersubband transition (ISBT) at conduction band, the latter makes it difficult to use the effective interband transition (IBT). To overcome this latter problem, the effect of the Sb was investigated because Sb would act as a band modulator from type-II to type-I. In 0.57 Ga 0.43 As 1-x Sb x /AlAs 0.48 Sb 0.52 single quantum well (SQW) samples with various Sb compositions x, were grown on GaAs substrates via AlAs 0.48 Sb 0.52 buffer layer. Their photoluminescence (PL) properties were examined to identify their band configurations. When the excitation laser power was increased, the PL property of In 0.57 Ga 0.43 As SQW sample, showed a larger blue shift than that of In 0.57 Ga 0.43 As 1-x Sb x (x≥0.13) ones. This indicates that the band configuration modulates from type-II to type-I when the antimonide composition is larger than 0.13. These findings indicate that new functional devices can be fabricated using a combination of IBT and ISBT.

TL;DR: In this paper , the authors developed a generally applicable synthesis route for these compounds and the obtained compounds were examined on their stability depending on the alkali metal and stabilizing additives used, whereby the use of appropriate crown-ethers allowed their isolation and characterization at room temperature.
Abstract: Abstract Alkali metal dihydrogen‐antimonides [M(L) x SbH2], short: alkali metal antimonides (M=Li, Na, K, Rb, Cs; 1: L=pmdta; 2: L=crown‐ether), were prepared from stibine and n‐Butyllithium, M(hmds) (hmds=hexamethyldisilazane) or MOtBu, respectively. We developed a generally applicable synthesis route for these compounds and the obtained compounds were examined on their stability depending on the alkali metal and stabilizing additives used, whereby the use of appropriate crown‐ethers allowed their isolation and characterization at room temperature. Moreover, the 1,4‐dioxane adduct [Na(dioxane) x SbH2] was the appropriate starting compound for the synthesis of the first primary silylstibane (Me3Si)3SiSbH2 (3) which was characterized by NMR and IR spectroscopy. Reaction of 3 with (Dipp2NacNac)Ga (Dipp2NacNac=HC{C(Me)N(Dipp)}2; Dipp=2,6‐iPr2C6H3) resulted in the formation of (Dipp2NacNac)GaH(SbHSi(SiMe3)3) (4) which was furthermore characterized by single crystal x‐ray diffraction.
