ABSTRACT
We find that the modulated temperature annealing of pulse-deposited high dielectric constant films, in which brief in situ elevated temperature anneals are performed after every deposition cycle, results in film densification, a reduction in interfacial layer thickness, and a strong improvement in electrical properties. The densification and improvement of electrical properties could not be achieved solely by postdeposition annealing at temperatures up to 850 °C. © 2004 American Institute of Physics.

    We studied photoluminescence of ∼30-nm-thick SrTiO3 film grown on Si substrate by radiofrequency (RF)-sputtering. While the as-grown film does not show any photoluminescence (PL) signal, we discovered that subsequent heat treatment can induce red (λ∼620 nm) and green (λ∼520...
