摘要: … The diffraction lines of the new phase, though broad, are consistent with a cubic spinel structure for the high-pressure phase. Following the α and β nomenclature for the two previously known phases of Ge3N4, we will use the term γGe3N4 to refer to this new phase. Following the discovery of this material in the diamond anvil cell, well-crystallized samples of up to 100 milligrams were … We note that in γ-Ge3N4, the tetrahedral Ge¿N bond lengths are about 0.045 ä longer than in β-Ge3N4, so that it may be a recurrent theme in highpressure spinels that …
