abstract = {Dysprosium scandate (DyScO3) thin films were deposited on
Si substrates using metal-organic chemical vapor deposition.
Individual source precursors of Dy and Sc were used and
deposition temperatures ranged from 480 to 700 degrees C.
Films were amorphous with low root mean square roughness (<=
2 A) and were stable up to 1050 degrees C annealing.
Electrical characterization yielded C-V curves with
negligible hysteresis (< 10 mV), high dielectric constant
(similar to 22), and low leakage currents. The electrical
properties of the DyScO3/SiOx/Si stacks were stable up to
800 degrees C for films on native oxide; however, this limit
increased to 900 degrees C for films on special chemically
grown oxide, suggesting further improvement with proper
diffusion barrier. (c) 2006 American Institute of Physics.},
