Single crystal preparation and properties of the AgGaGeS sub(4-AgGaGe) sub(3)Se sub(8 solid solution)

Phase equilibria in the AgGaGeS sub(4-AgGaGe) sub(3)Se sub(8 system were investigated using differential-thermal analysis and phase X-ray diffraction. A continuous solid solution series was discovered in the system, and the mechanism of the formation of these solid solutions was determined. Single c...

Zusammenfassung:Phase equilibria in the AgGaGeS sub(4-AgGaGe) sub(3)Se sub(8 system were investigated using differential-thermal analysis and phase X-ray diffraction. A continuous solid solution series was discovered in the system, and the mechanism of the formation of these solid solutions was determined. Single crystals of the solid solutions were grown by the Bridgman-Stockbarger method. The crystals are of n- or p-type conductivity and their bandgap energy varies from 2.25 to 2.80 eV.)
