CuGe 2 P 3 is a p-type semiconductor with zincblende structure. Ge 3 P 4 is soluble up to 35 mole % in CuGe 2 P 3 . Lattice parameters of CuGe 2 P 3 + 0.2 Ge 3 P 4 have been determined at elevated temperatures from room temperature to 873 K using the x-ray diffraction profiles ( 111), ( 200), ( 220)
Infrared reflectivity spectra of (Cu,GeSe,)l-, (CuGe,P,), mixed crystals with z = 0.1 and 0.2 are measured in t h e wave-number range from 180 t o 4000 cm-l. An analysis of the spectra reveals contributions from five vibrational modes and from free carriers t o the reflectivity. The results are comp
