- Synthesis Germanium Ball
For the fabrication of Si/Ge heterojunctions, a pre-requisite is the germanium ink, which necessitates the need for germanium nanoparticles. Various methods have been employed in synthesizing germanium nanoparticles such as gas decomposition [18], chemical route of reducing Ge salts [19,20], laser synthesis [21] and thermolysis [22].

Weigh 653 mg of Ge (9 mmol) and insert into the tube on top of potassium metal. Carefully crimp the open end of the Nb tube using vise-grips and slightly bend the edge. Repeat for the three other Nb tubes. Place all four tubes in a jar [under inert gas], close the jar and place it in the box antechamber in order to bring out.

Within this context, the LAG synthesis of germanes (GeR 4) directly from germanium metal or germanium dioxide (GeO 2) was recently reported . Milling of germanium powder or GeO 2 with quinone or catechol, respectively, in the presence of a Lewis base under LAG conditions, produced a series of germanium complexes (see Scheme 5).
