Abstract:
ZnGeN 2 as exemplary compound for II-IV-N 2 materials allows fascinating insights into this class of materials that can be thought of as earth-abundant alternative to wurtzite-type III–V semiconductors. A classical route to achieving ZnGeN 2 is through the ammonolysis reaction of Zn 2 GeO 4 at higher temperatures. Using a combination of X-ray and neutron powder diffraction together with chemical analyses, a systematic study of the influences of time and temperature on this reaction, yielding in the formation of zinc germanium oxide nitrides in a wurtzite-type structure with variable elemental compositions is presented. This further allows to identify the underlying reaction mechanism of this ammonolysis reaction.
