High dielectric constant (high-k) ZrO2 films have been deposited on straine
d Si0.91Ge0.09 epitaxial layers using zirconium tetratert butoxide [Zr(OC(C
H3)(3))(4)] by microwave plasma enhanced vapour deposition technique at a l
ow temperature. Deposited ZrO2 films show good electrical properties and ar
e suitable for microelectronic applications.
