AI Article Synopsis

  • The study examines anion photoelectron spectroscopy and theoretical research related to two compounds, MnGe and MnGe, revealing their electron detachment energies of approximately 2.58 eV and 2.88 eV, respectively.
  • Both compounds have symmetric structures characterized by a manganese (Mn) atom positioned on a pentagonal bipyramid MnGe.
  • The findings suggest that extending MnGe to a different configuration could lead to the development of a novel Mn-doped germanium nanostructure, offering potential for new applications.

Article Abstract

We present joint anion photoelectron spectroscopy and theoretical studies for MnGe and MnGe. Experimental results show that MnGe and MnGe have vertical electron detachment energies of 2.58 ± 0.08 and 2.88 ± 0.08 eV, respectively. Both MnGe and MnGe have symmetric structures with a Mn atom attached to a pentagonal bipyramid MnGe. Both MnGe and MnGe have symmetric structures, which can be considered as two MnGe tetragonal bipyramids sharing a MnGeMn face. According to chemical bonding analyses, MnGe could be considered as a (Mn)(MnGe) complex. Theoretical calculations predict that the extension of MnGe to MnGe may be able to produce a new type of Mn-doped germanium nanostructure.

Article Synopsis
  • The study explores the interface structure, magnetism, and electronic properties of a heterojunction made from two all-Heusler alloys, CoMnGe and CoTiMnGe, using density functional theory calculations.
  • CoMnGe is identified as a half-metal with a high magnetic moment, while CoTiMnGe is a narrow-band gap semiconductor and may be useful as a photocatalyst.
  • The presence of interface states weakens ideal spin-polarization, but the CoCo-TiGe-B structure shows a significant spin-polarization of 94.31%, indicating potential for high-performance magnetic tunnel junctions.

The synthesis, thermolysis, and surface organometallic chemistry of thermolytic molecular precursors based on a new germanosilicate ligand platform, -OGe[OSi(OBu)], is described. Use of this ligand is demonstrated with preparation of complexes containing the first-row transition metals Cr, Mn, and Fe. The thermolysis and grafting behavior of the synthesized complexes, Fe{OGe[OSi(OBu)]} (FeGe), Mn{OGe[OSi(OBu)]}(THF) (MnGe) and Cr{OGe[OSi(OBu)]}(THF) (CrGe), was evaluated using a combination of thermogravimetric analysis; nuclear magnetic resonance (NMR), ultraviolet-visible (UV-Vis), and electron paramagnetic resonance (EPR) spectroscopies; and single-crystal X-ray diffraction (XRD).

Article Synopsis
  • Mn5Ge3 is a ferromagnetic material that could improve spin injection and detection in electronic devices, specifically on Ge/SiGe quantum well structures.
  • Researchers formed Mn5Ge3 contacts through solid-state synthesis and confirmed their growth using X-ray diffraction and electron microscopy techniques.
  • Electrical tests indicate that Mn5Ge3-based contacts are effective p-type contacts with a low Schottky barrier height of 0.10 eV and contact resistance around 1 kΩ, showing that their properties can be tuned with gate voltage.

Large size epitaxial thin films of ferromagnetic CoMnGe full Heusler alloy are grown over MgO(100) substrate by using pulsed laser deposition technique under optimized growth conditions. Metallic behavior is confirmed from the longitudinal resistivity-temperature data, while a minimum in the resistivity at ∼25 K is attributed to the disorder-induced weak localization effect. Importantly, a dominating intrinsic anomalous Hall conductivity value of ∼21 S cm against an overall anomalous Hall conductivity value of ∼36 S cm at the room temperature has been estimated for the epitaxial CoMnGe film.

Reactions of the ethylene hydride complex -[(dmpe)MnH(CH)] (1) with secondary hydrogermanes HGeR at 55-60 °C afforded the base-free terminal germylene hydride complexes -[(dmpe)MnH(GeR)] (R = Ph; 2a, R = Et; 2b). Room temperature reactions of 2a or 2b with an excess of the primary hydrogermanes HGeR' (R' = Ph or Bu) afforded -[(dmpe)MnH(GeHR')] (R' = Ph; 3a, R' = Bu; 3b) in rapid equilibrium with small amounts of 2a/b, as well as the digermyl hydride complex -[(dmpe)MnH(GeHR')] {R' = Ph (4a) or Bu (4b)} and the -hydrogermane germyl complex -[(dmpe)Mn(GeHR')(HGeHR')] {R' = Ph (5a) or Bu (5b)}. Pure 3b was isolated from the reaction of 2b with HGeBu, whereas 3a decomposed readily in solution in the absence of free HGePh, and a pure bulk sample was not obtained.
