Abstract— The processes occurring during the solid-state synthesis of germanium-doped lithium titanium phosphate have been studied. The formation of LiTi2 – xGex(PO4)3 has been shown to proceed through the titanium pyrophosphate formation followed by its transformation into materials with the NASICON structure. The process is completed at ...
Although the first studies of Zintl ions date between the late 1890's and early 1930's they were not structurally characterized until many years later. 1,2 Their redox chemistry is even younger, just about ten years old, but despite this short history these deltahedral clusters ions E 9 n-(E = Si, Ge, Sn, Pb; n = 2, 3, 4) have already shown interesting and diverse …
I'm just scratching an itch here but "you never know" so here is a dedicated page because the comments thread got quite excessive on the TTLers project page. As the name implies, it's a strip of PCB with logic functions soldered on it. A bit like a LED strip but not flexible and, instead of emitting light, it's like a cut-to-measure strip to provide basic, identical …
The synthesis and properties of the hybrid organic/inorganic germanium perovskite compounds, AGeI3, are reported (A = Cs, organic cation). The systematic study of this reaction system led to the isolation of 6 new hybrid semiconductors. Using CsGeI3 (1) as the prototype compound, we have prepared me …
For the fabrication of Si/Ge heterojunctions, a pre-requisite is the germanium ink, which necessitates the need for germanium nanoparticles.
