Highly polarizable c-axis-oriented SrBi4Ti4O15 (SBTO) films with permi
ttivity of 53 epsilon(0) were grown on (100)Pt/(100)MgO substrates by
eclipse pulsed laser deposition (PLD) method. By mechanically contacti
ng a p(-)-Si tip onto the SBTO surface and using a Pt underlying layer
as the base electrode, the inverted metal-oxide semiconductor (MOS) s
tructures were prepared. Although the experiment is still in the preli
minary stage, the held-induced carrier density at the Si surface reach
ed as high as about5.0x10(12) cm(-2) for 5 V applied voltage, being ab
out 10 times higher than that of the metal/SiO2/Si MOS diode.
