Good-quality polycrystalline BaTiO3 thin films are deposited on MgO substrates by pulsed laserdeposition. The deposition parameters are optimized to achieve optical-quality films with an attenuation coefficient of 4 dB/cm at the 633-nm wavelength. Thin-film electro-optic Mach-Zehnder modulators are fabricated with standard lithography and ion-beam etching.(More)
We present a systematic study on the nanoscale chemistry around misfit dislocations (MDs) in ferroelectric thin films, to attribute their effects on the reported degradation of physical properties.[1] The quality of the interface was examined using High Resolution Transmission Electron Microscopy (HRTEM) investigations, acquired on the following model(More)
