Description 465-469
The quaternary semiconductor compound Ag2FeGeSe4, belonging to the system I2-II-IV-VI4 and synthesized by the melt
and anneal technique, was structurally characterized by Rietveld refinement of the powder X-ray diffraction data. This
compound crystallizes in the orthorhombic space group Pmn21, Z = 4, with unit cell parameters a = 7.6478(1) Å, b =
6.5071(1) Å, c = 6.4260(1) Å, and V = 319.79(1) Å3, in a wurtzite-stannite arrangement with a Cu2CdGeS4-type structure.
The Debye temperature (D) estimated for this compound was 194 K.
