摘要
The spinel structure of Ge3N4 is compared with that of beta-Ge3N4 and a cubic defect zinc-blende structure recently considered possible for C3N4. The beta phase is suggested to be a possible precursor phase to the spinel structure. Electronic structure calculations reveal that the spinel structure is a subtle extension of the defect zinc-blende phase in which the Ge atoms attempt to connect into the conventional zinc-blends structure.
