| Abstract: | Terahertz spectroscopy is applied for characterizing the high frequency transport of electrons in polycrystalline ZnO films deposited by spray pyrolysis. Electromodulation of the charge carrier density provides the frequency dependent conductivity of the electron gas. Amplitude and phase of the high frequency response are well reproduced by the Drude–Smith model. |
