Abstract Infrared reflectivity spectra of p -type Ag 6 Ge 10 P 12 single crystals were measured at room temperature in the wavenumber range from 180 to 4000 cm -1 . Fits to a dielectric function including contributions from lattice oscillators and free carriers gave the parameters of five lattice vibrational modes and an effective hole mass of m p / m o = 2.3.

The infrared reflectivity spectra were recorded at room temperature in the wavenumber range ν=180 to 4000 cm −1 using incident radiation polarized parallel to the respective crystal axes and perpendicular to the plane of incidence. The resulting spectra for the two polarization directions E∥a 0 and E∥b 0 are shown for the wavenumber range ν=180 to 500 cm −1 . No further structures were observed at ν>500 cm −1
