Thermolysis and Mass Spectra of Polymeric Germanium Hydride Produced by γ-Radiolysis.

Abstract TGA, MS and DSC of a solid polymeric Ge hydride, obtained by γ-radiolysis of GeH 4 , are reported. Upon heating, it undergoes two successive weight losses at 463 and 1173 K. At 948 K two crystal phases are formed, one of them is pure germanium. Some comparisons with a-Ge: H produced via RF sputtering or glow discharge are reported.
