摘要：

Through terahertz time-domain spectroscopy, negative imaginary conductivity is observed in In-rich AlInN film grown by metal-organic chemical-vapor deposition for frequencies from 0.2 to 2.0 THz. This non-Drude behavior is explained based on the electron back-scattering theory of Smith [Phys. Rev. B 65, 115206 (2002)]. Comparing with binary semiconductor InN, potential fluctuations produced by composition inhomogeneity and alloy scattering of carriers make In-rich AlInN alloy easier to be subjected to non-Drude behavior in electrical performance.
