摘要：

Al-doped TiO2 thin films grown on Si(100) by atomic layer deposition has been investigated as a potential high dielectric constant insulator in the application of microelectronics. The film thickness is determined by spectroscopy ellipsometry and transmission electron microscopy. X-ray photoelectron spectrometry is used to characterize the chemical composition and bonding states. The relative permittivity (k) determined by C-V measurement is 14.6. Moreover, ultralow hysteresis of C-V curves has been demonstrated for the Al-doped TiO2 film with few instable-trapped charges.
