Synthesis, Structure and Physical Properties of the Sodium‐Rich Phosphidogermanate Na8GeP4

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 649, Issue 20, October 16, 2023., 2023
Abstract Sodium ion conductor materials hold promise to be an affordable substitute for ever growing lithium demand. To achieve high ionic conductivity in all‐solid state ion conductor materials, fundamental understanding of the atomic structure of the materials as well as the structure‐property relationship are basic prerequisites.

Single‐Source Precursors for the Chemical Vapor Deposition of Iron Germanides

open access: yesEuropean Journal of Inorganic Chemistry, Volume 26, Issue 29, October 12, 2023., 2023
The reaction of GeCl2 ⋅ 1,4‐dioxane with Fe2(CO)9 gives [Cl2GeFe(CO)4]2, Cl2Ge[Fe2(CO)8]Ge[Fe2(CO)8] or Ge[Fe2(CO)8]2, depending on the educt ratio. [Cl2GeFe(CO)4]2, Ge[Fe2(CO)8]2 and Me₂iPr₂NHC ⋅ GeCl2 ⋅ Fe(CO)4 were characterized in their thermal decomposition behavior and applied as single source precursors in chemical vapor deposition, resulting in

Untersuchung von Ladungstransferprozessen in einer kovalent verknüpften [Ge9]‐Cluster‐Imin Dyade

open access: yesAngewandte Chemie, Volume 135, Issue 29, July 17, 2023., 2023
Chemochrome Cluster. Silylierte [Ge9]‐Cluster bilden ein neuartiges Chromophorsystem. Die Protonierung einer kovalent an den Cluster gebundenen Imineinheit führt zu einem intensiven Farbwechsel von rot nach grün. Transiente Absorptionsspektroskopie und DFT‐Rechnungen an der protonierten Form zeigen eine ultraschnelle Dynamik bei Lichtanregung, die zu ...

Probing Charge‐Transfer Processes in a Covalently Linked [Ge9]‐Cluster Imine Dyad

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 29, July 17, 2023., 2023
Silylated [Ge9] clusters form a novel type of chromophore system. Protonation of a covalently cluster‐bound imine moiety results in an intense color change from red to green. Transient absorption spectroscopy and DFT calculations on the protonated form reveal ultrafast dynamics upon photoexcitation leading to a charge‐transfer between the cluster and ...

GeSn on Insulators (GeSnOI) Toward Mid-infrared Integrated Photonics

open access: yesFrontiers in Physics, 2019
In recent years, Ge and Ge1−xSnx materials and devices have achieved rapid progress in integrated photonics. However, conventional heteroepitaxy of active photonic devices compromises the area on Si for CMOS electronics, limiting the scale of integration.
