Abstract
The influence of carrier-free surface layers on infrared reflection spectra of metallic oxides has been explored using model calculations on two-layer systems. Reflectivity minima are found at LO phonon frequencies. Comparison is made with preliminary experimental data from Sb-doped SnO 2 ceramics and Na 0.6WO 3 single crystal surfaces oxidised in air at 500°C.
